We are just perfecting it.
The Last Performance Device You'll Ever Need
For a hundred years, men searched for an honest answer to a private question: how do I feel more confident, more capable, more present in the moments that matter? Sergg Device is that answer — refined from a century of vacuum engineering, protected by our own patents, and built for the man who refuses to settle. This isn't another gadget in a drawer. It's the one device that makes every other option obsolete.
Built For Pleasure.
Engineered For Confidence.
Heightened Pleasure
A precision vacuum gently draws blood flow exactly where it matters — fuller, firmer, more electric sensation for you, and an experience she'll be thinking about for days.
Fuller, Firmer, Bigger
The patented vacuum effect produces temporary added size and firmness on demand — so you walk into the bedroom thicker, harder, and completely in command.
Quiet Confidence
Confidence is the ultimate aphrodisiac. Men who use Sergg walk taller, perform freely, never second-guess themselves — and a woman feels that certainty the instant he touches her.
Proudly Patented — U.S. Patent No. 11,833,072 B2
Sergg was conceived in America, by an American, and secured through U.S. Patent No. 11,833,072 B2 — a continuation of our earlier 2020 filing. It is, in the truest sense, our own.
When capable minds, working independently, arrive at the same idea, it is usually because the idea was right. Others have since pursued similar ground, and we take that as affirmation rather than rivalry — we were simply there first. What we built, we built for every man: whoever he is, wherever he is from.
Every Sergg is machined and finished to the standard you would expect of a clinical instrument — the same discipline, aimed at a far more enjoyable purpose.

Every Sergg product is built on the same patented foundation. Here are the ones men reach for first.
She fell for him
before she ever knew why.
The why was Sergg.
Some nights, she won’t want it to end.
The change starts before he even touches her.
Wake up. Sergg. Repeat.
Men describe the same quiet transformation: steadier confidence, a sense of being fully in their body, and the freedom to stop worrying and start enjoying. Whether he's pleasuring himself after a long day or sharing a slow, unhurried night with his partner, the experience feels fuller, firmer, more alive.
And confidence is contagious. When a man feels sure of himself, he touches differently, lingers longer, leads. His partner feels desired, savored, unforgettable. That's the real promise of Sergg — not just a better night, but a better version of the man.

Claim Yours Now→The Story Behind The Brand.
Born from a simple belief: every man deserves to feel unstoppable.
Sergg Device began with a frustration shared by millions of men but spoken aloud by almost none — that confidence in the bedroom should never be left to chance. Somewhere between the cheap drugstore gimmicks and the cold, clinical medical catalogs, an entire category of men had been forgotten: men who simply wanted to feel their best, perform freely, and bring their partner a night neither would forget.
So we engineered something better than anything before it — a device that delivers real, repeatable results, feels premium in the hand, and carries zero shame. We studied a century of vacuum engineering, stripped away everything that didn't work, and rebuilt the entire concept around one obsession: the man who refuses to settle. The result is Sergg Device — and there is, quite simply, nothing else like it on earth.
We are just perfecting it.
The Patent Behind The Device
Sergg Device is protected by U.S. Patent No. 11,833,072 B2, a continuation of our earlier filing US 2020/0146870 A1 — an American invention, documented and defended well before the idea became familiar. We are humbled that something we committed to so early has proven so enduring.
There is a certain honor in being echoed. When a later application sought similar ground, our earlier patents were recognized as the established prior art — not a contest won, but quiet confirmation that good thinking tends to converge. Separate minds reaching the same conclusion is, more often than not, a sign the conclusion was correct. We were there first, and we hold that lightly and gratefully.
In the end, the patent matters for one human reason: when you choose Sergg, you choose the original — conceived in America, refined with care, and made for every man, whoever he is and wherever he calls home.
Confidence, made effortless — for every man, of every background.
We serve men of all races, ages, and walks of life who want to take ownership of their pleasure and confidence. No judgment, no clinical coldness — just a beautifully made product that works, and a brand that treats you like the man you already want to be.
Whether you're flying solo at the end of a long week or sharing an unhurried night with someone you can't keep your hands off, Sergg makes every moment count — and makes every other option in your drawer unnecessary.

The History Of The Vacuum Device
Two stories, one invention — the medical pursuit of restoring function, and the human pursuit of pleasure. Sergg is where both finally meet.
The First Idea
An early American medical text describes a crude vacuum apparatus meant to encourage blood flow and engorgement — the conceptual seed of every vacuum device that followed.
The First Patent
Inventor Otto Lederer is credited with one of the earliest patents for a vacuum erection device, formalizing the principle of applying negative pressure to draw blood into the tissue.
The Modern Device Is Born
American entrepreneur Geddings D. Osbon Sr., frustrated by his own struggles, developed the "Osbon ErecAid," refining the device into a practical, repeatable system and earning the title of father of the modern vacuum erection device.
Medical Recognition
The vacuum erection device gained formal recognition as a legitimate, non-invasive option for men managing erectile difficulty — pairing the vacuum chamber with a constriction ring to sustain firmness.
Two Worlds Diverge
Clinicians embraced vacuum devices for erectile management and, later, penile rehabilitation after prostate surgery. Meanwhile a parallel world of pleasure-focused pumps emerged — built not to treat, but to enhance sensation, size, and play.
The Culmination: Sergg Device
A century of seals, gauges, materials, and lessons distilled into one patented design that finally does justice to both legacies — the best performance device ever created, and the one that renders everything before it obsolete.
Medicine & Pleasure: Two Roads, One Device
For decades the vacuum device lived a double life. In clinics it was a discreet, drug-free way to help men restore firmness, and it later found a role in helping men recover tissue health after prostate surgery — a practice clinicians call penile rehabilitation. In bedrooms, a different device flourished: one designed purely to amplify pleasure, deliver temporary fullness, and turn an ordinary night into something memorable.
Sergg was built by people who studied both traditions and refused to compromise either. We borrowed the precision and safety of the medical world — body-safe FDA-compliant materials, controlled pressure, comfortable seals — and married them to the sensual, confidence-building purpose of a pleasure device. The result feels clinical in its quality and indulgent in its experience. To be clear: Sergg is a wellness and pleasure product, not a medical device, and any added size or firmness is temporary. But its engineering DNA is drawn from the very best of a hundred years of human ingenuity.
Every Toy Led To This One
Men have chased pleasure with invention for thousands of years. Here's the journey — and where it finally ends.
Antiquity
The earliest phallic objects and rings date back thousands of years. In ancient China, men reportedly fashioned rings worn at the base to sustain firmness — the distant ancestor of the modern cock ring.
19th–20th Century
The industrial age brought engineering to intimacy: vacuum apparatuses, early massagers, and the first mass-produced personal devices, originally marketed for "wellness."
1996 — The Doll Era
Lifelike companion dolls entered the modern market, pushing realism and silicone craftsmanship forward and proving demand for premium, body-safe materials.
1998 — The Stroker Revolution
The patented male stroker (most famously the Fleshlight, patented by Steve Shubin) redefined solo pleasure for men and became a cultural icon of the category.
Late 1990s — Internal Pleasure
Prostate-focused massagers introduced a new dimension of male pleasure, expanding what men understood their own bodies could feel.
2010s — The Smart Era
App-connected vibrating strokers, rings, and pumps brought sensors and automation to the bedroom — convenient, but rarely premium, and rarely patented innovation.
How It Works
A sealed chamber, a gentle drop in pressure, and more blood flows where it counts — so you look and feel fuller and firmer. The effect is temporary and eases once the seal is released.
How To Use Sergg Device
Four easy steps to a fuller, firmer, more confident you. Used consistently and responsibly, the experience only gets better.
Prep & Lubricate
Apply a generous amount of water-based lubricant around the base seal for a comfortable, airtight fit. Comfort always comes first.
Position & Seal
Place the chamber and press gently to form a complete vacuum seal. The ergonomic design handles alignment for you — effortless and intuitive.
Build Pressure Gradually
Build vacuum slowly, watch the gauge, and stop the moment you reach a firm, comfortable level. Never exceed the recommended pressure — patience delivers the best results.
Release & Enjoy
Press the quick-release valve, remove the chamber, and step into the moment fuller, firmer, and completely in control — solo or shared. Clean thoroughly after every use.
Who Is Sergg Device?
An independent company with a single-minded obsession: the perfect performance device.
Sergg Device is the company behind the most advanced patented vacuum performance device for men. We are not a sprawling conglomerate hiding behind a dozen sub-brands, and we are not a drop-shipper slapping a logo on someone else's mold. We are an independent, focused company that designs, patents, and stands behind one extraordinary product line — and we answer only to the men and couples who trust us.
That independence is our greatest strength. It means every decision we make is in service of the product and the customer, never a distant shareholder. It's why we invested in securing our own patents, why we insist on FDA-compliant, body-safe materials, and why we hold ourselves to the highest production standard possible rather than the cheapest one available.
Founded to fix what no one else would.
Sergg Device was formed because its founders saw a category that had stalled. The medical world treated the vacuum device as a clinical afterthought; the novelty market treated it as a throwaway gimmick. No one was building a device that respected the man using it — premium, safe, effective, and free of shame. So we set out to build exactly that, and to own the innovation outright through our own patents.
From day one the goal was never to be the biggest. It was to be the best — to build the one device that could stand beside medical-grade equipment on quality while delivering the pleasure and confidence men actually want.
Milestones
A focused company moves deliberately. Here is the shape of our story — ready for your real dates and achievements.
One Idea That Wouldn’t Let Go
It began with a simple frustration: the devices on the market were nothing more than a plain cylinder and a hand pump — unchanged for generations. Our founder set out to reinvent the entire thing from the ground up, deciding what to keep and what to reimagine.
Three Inventions, Then A Second Device
The redesign produced what no one else had: angled adapters, precision weights, and the four-point threading system embedded directly into the cylinder. The ideas came so fast they yielded not one patentable device, but two.
Two Patents Granted
After years of perseverance — and the very real challenge of funding an invention alone — both devices were awarded United States patents, including U.S. Patent No. 11,833,072 B2.
Validation From Unexpected Places
Years after our patents were secured, the U.S. Patent Office’s own records showed others independently arriving at the same ideas we already owned. For a self-funded inventor who had nearly set the project aside, it was the push to move forward at full throttle.
Sergg Device Project 1
The first complete product is here: three adapters, two cylinders, and three weights — engineered, patented, and owned outright. The firstborn of a growing family, with Project 2 already taking shape.
A House Built To Grow.
Sergg Device isn’t a single product — it’s a lineage. Each generation gives rise to the next.
Soluble Advancement Core Group LLC
The parent company — the foundation from which everything grows, and the origin of the Sergg name itself.
Sergg Device®
The registered brand the world will know — the identity under which every device is born and carried forward.
Sergg Device Project 1
The complete first product — three adapters, two cylinders, three weights. Simple name. Powerful device. And only the beginning: Project 2 is already on its way.

Standing on our own — and ahead.
As a standalone company, Sergg's success is measured not in the size of a corporate empire but in the strength of a single, focused promise kept thousands of times over. Our independence lets us reinvest in what matters: better materials, tighter manufacturing tolerances, stronger patent protection, and the kind of customer care that larger companies abandon. It is because of Sergg Device that men will finally have access to a performance device worthy of them — and the best time of their lives.

Sergg Loyalty Replacement Program

Each part is replaced at 35% off its own full price — the bundle you bought it in doesn't change the replacement price.
What's Covered — And What Isn't
Nearly everything is covered for as long as you own your Sergg Device. A break, a crack, a malfunction, everyday wear, a blemish — even damage you caused yourself. If something is wrong when your order first arrives, the 14-Day Arrival Guarantee replaces it free. After that, the Loyalty Replacement Program brings any adapter or cylinder back to brand-new for up to 35% off, as many times as you ever need. Weight sets are solid stainless steel — built to outlast the device itself — so they sit outside the program; if a question ever comes up about your weights, just reach out.
Only two things fall outside this: items that are lost and items that are stolen — the program covers components you still own. Keep your original as a backup; there is nothing to send back. Claims are honored for the original purchaser, so to begin you simply confirm your order number from your order confirmation — that number becomes your claim number.
Your Loyalty Replacement price is a standing Loyalty discount off the part's current price — adapters and cylinders at up to 35% off — whether you paid full price, received it at a discount inside a bundle, or through any other offer. There is nothing to send back and no return shipping to cover; we ship your replacement in plain, unmarked packaging. The Sergg Device is a personal-care product and is not a medical device.
No one else does this. It's simply how Sergg Device looks after the people who trust us — we have your back, for life.

Title and risk of loss for physical Products pass to you upon our delivery to the carrier. You agree not to initiate any fraudulent, abusive, or unwarranted chargeback; we reserve the right to dispute and recover on improper chargebacks, including associated costs and fees.
10. Shipping, Discretion & Risk of Loss
We ship using discreet packaging where offered. Delivery dates and times are estimates only and are not guaranteed. We are not responsible for delays, losses, duties, or damage caused by carriers, customs, incorrect addresses provided by you, or events beyond our reasonable control. You are responsible for ensuring importation and receipt of adult Products are lawful at your delivery address.
11. Returns, Refunds & Restocking
For reasons of hygiene, health, and safety, intimate and personal-use Products are final sale and non-returnable and non-refundable once delivered, except where a Product arrives demonstrably defective or damaged on arrival, or where a refund or remedy is required by applicable non-waivable law. Claims for a Product that is defective or damaged on arrival must be submitted within the period and in the manner described in our returns information, with proof of purchase and supporting documentation. Where we accept a return or offer a remedy, we may, at our option and to the extent permitted by law, provide a replacement, repair, store credit, or refund, and may apply reasonable restocking or handling conditions for eligible non-intimate items. This Section does not limit any rights that cannot be waived under applicable law.
12. Limited Warranty
We warrant only that, at the time of delivery, a Product will be free from material manufacturing defects under normal, intended personal use for the limited warranty period (if any) stated in the materials accompanying the Product or on the Site. This limited warranty is the sole and exclusive warranty we provide, extends only to the original purchaser, and is non-transferable. It does not cover normal wear, cosmetic changes, or any damage, malfunction, or condition resulting from misuse, abuse, accident, alteration, improper cleaning or storage, use of unauthorized accessories or accessory combinations, failure to follow instructions, or use contrary to the Product’s intended purpose. Your sole and exclusive remedy under this limited warranty is, at our option and to the extent permitted by law, repair, replacement, or refund of the purchase price of the affected Product.
Sergg Loyalty Replacement Program. As a separate, discretionary courtesy beyond the limited warranty above, we may offer original purchasers the ability to obtain replacement components at a reduced Loyalty price. This program is provided for personal ownership only and is intended for the original purchaser’s own Device. When filing a claim you confirm that you are the original, rightful owner of the order associated with the claim. We may verify ownership and may decline or reverse claims, or limit, suspend, or modify the program, where we detect resale, sharing of order credentials, or other activity inconsistent with personal ownership or these Terms. The Loyalty price is a courtesy discount and not a warranty entitlement; nothing in this program enlarges the limited warranty or guarantees future availability.
13. Disclaimer of Warranties
EXCEPT FOR THE LIMITED WARRANTY EXPRESSLY STATED IN SECTION 12, AND TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE SITE, ALL CONTENT, AND ALL PRODUCTS ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS AND WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. TO THE FULLEST EXTENT PERMITTED BY LAW, WE SPECIFICALLY DISCLAIM ALL IMPLIED WARRANTIES, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING, USAGE, OR TRADE PRACTICE. WE DO NOT WARRANT THAT THE SITE WILL BE UNINTERRUPTED, SECURE, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS, THAT ANY DEFECT WILL BE CORRECTED, OR THAT ANY PRODUCT WILL MEET YOUR EXPECTATIONS OR ACHIEVE ANY PARTICULAR RESULT. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU; IN THAT CASE, ANY LEGALLY REQUIRED WARRANTY IS LIMITED IN DURATION AND SCOPE TO THE MINIMUM PERMITTED BY LAW.
14. Limitation of Liability
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL SERGG OR ITS OWNERS, OFFICERS, MEMBERS, EMPLOYEES, AGENTS, SUPPLIERS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, OR FOR ANY PERSONAL INJURY, EMOTIONAL DISTRESS, OR PROPERTY DAMAGE, ARISING OUT OF OR RELATING TO THE SITE, THE CONTENT, ANY PRODUCT, OR THESE TERMS, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, WARRANTY, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
TO THE FULLEST EXTENT PERMITTED BY LAW, THE TOTAL AGGREGATE LIABILITY OF SERGG AND THE PARTIES LISTED ABOVE FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SITE, THE CONTENT, ANY PRODUCT, OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNT YOU ACTUALLY PAID TO US FOR THE SPECIFIC PRODUCT GIVING RISE TO THE CLAIM IN THE THREE (3) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS (US$100). THE FOREGOING LIMITATIONS APPLY TO THE FULLEST EXTENT PERMITTED BY LAW. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS OR THE EXCLUSION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU; NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW, INCLUDING LIABILITY FOR FRAUD OR FOR DEATH OR PERSONAL INJURY CAUSED BY OUR PROVEN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT WHERE SUCH LIABILITY MAY NOT LAWFULLY BE LIMITED. YOU AGREE THAT THESE LIMITATIONS ARE A FUNDAMENTAL BASIS OF THE BARGAIN BETWEEN US AND WILL SURVIVE EVEN IF ANY REMEDY FAILS OF ITS ESSENTIAL PURPOSE.
15. Indemnification
To the fullest extent permitted by law, you agree to indemnify, defend, and hold harmless Sergg and its owners, officers, members, employees, agents, suppliers, and affiliates from and against any and all claims, demands, actions, liabilities, damages, losses, judgments, fines, penalties, costs, and expenses (including reasonable attorneys’ fees and costs) arising out of or relating to: (a) your access to or use of the Site, Content, or any Product; (b) your misuse of any Product or failure to follow instructions, warnings, or safe-use requirements; (c) your violation of these Terms or any applicable law; (d) your violation of the rights of any third party; or (e) any content or information you submit. We reserve the right, at our own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, and you agree to cooperate with our defense. This Section survives termination of these Terms.
16. Third-Party Links & Services
The Site may contain links to or integrations with third-party websites, payment processors, or services that we do not own or control. We provide these for convenience only and are not responsible for the content, policies, security, or practices of any third party. Your dealings with any third party are solely between you and that third party.
17. Privacy
Your use of the Site is also governed by our Privacy Policy, which describes how we collect, use, and protect information. By using the Site, you consent to the practices described in the Privacy Policy.
18. Dispute Resolution — Binding Arbitration & Class-Action Waiver
Please read this Section carefully — it affects how disputes are resolved and, in many cases, requires individual arbitration instead of court litigation or a jury trial.
(a) Informal resolution first. Before commencing any formal proceeding, you agree to first contact us and provide a brief written description of the dispute and your contact information, and to attempt in good faith to resolve the dispute informally for at least sixty (60) days. Many concerns can be resolved quickly this way.
(b) Agreement to arbitrate. To the fullest extent permitted by applicable law, and except as provided below, you and Sergg agree that any dispute, claim, or controversy arising out of or relating to the Site, the Content, any Product, or these Terms — including their existence, validity, interpretation, breach, or termination — that is not resolved informally will be resolved by final and binding individual arbitration, rather than in court, administered under the rules of a recognized, neutral arbitration provider then in effect, as modified by these Terms. The arbitration shall be conducted by a single neutral arbitrator. Judgment on the award may be entered in any court of competent jurisdiction. The Federal Arbitration Act governs the interpretation and enforcement of this Section.
(c) Class-action and jury-trial waiver. To the fullest extent permitted by applicable law, you and Sergg agree that each may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding. The arbitrator may not consolidate more than one person’s claims and may not preside over any form of class or representative proceeding. You and Sergg are each waiving the right to a trial by jury and the right to participate in a class action, to the extent permitted by law.
(d) Exceptions. Notwithstanding the above, either party may (i) bring an individual claim in a small-claims court for disputes within that court’s jurisdiction, and (ii) seek injunctive or other equitable relief in a court of competent jurisdiction to protect intellectual-property or proprietary rights. This Section does not require arbitration of any claim that, as a matter of law, cannot be subject to a pre-dispute arbitration agreement.
(e) Severability of this Section; consumer protections. If the class-action waiver in subsection (c) is found unenforceable as to a particular claim, that claim (and only that claim) shall be severed and proceed in court, while all other claims proceed in arbitration. If applicable law prohibits enforcement of any part of this Section against you as a consumer, that part shall not apply to you, and the dispute shall instead proceed as permitted by such law. Nothing in this Section, and nothing elsewhere in these Terms, requires that any aspect of the resolution of a dispute be kept confidential, and nothing waives any right or protection that applicable law makes non-waivable.
19. Governing Law & Venue
These Terms and any dispute arising out of or relating to them, the Site, the Content, or any Product are governed by the laws of the State of Nevada and applicable United States federal law, without regard to conflict-of-laws principles. Subject to the arbitration provisions in Section 18, and to any mandatory protections that applicable law affords you as a consumer, the exclusive venue for any permitted court proceeding shall be the state and federal courts located in the State of Nevada, and you consent to the personal jurisdiction of those courts — provided that nothing in this Section deprives you of the benefit of any mandatory provision of the consumer-protection law of your home jurisdiction that cannot be waived by agreement.
20. Time Limitation on Claims
To the fullest extent permitted by applicable law, any claim or cause of action arising out of or relating to the Site, the Content, or any Product must be commenced within one (1) year after the claim or cause of action accrues; otherwise, that claim or cause of action is permanently barred. Where applicable law does not permit a one-year limitation, the shortest period permitted by that law shall apply.
21. Force Majeure
We will not be liable or responsible for any failure or delay in performance caused by events beyond our reasonable control, including acts of God, natural disasters, epidemics or pandemics, war, terrorism, civil unrest, governmental action, labor disputes, carrier or supplier failures, payment-processor or internet outages, or other force-majeure events.
22. Changes to These Terms or the Site
We may modify these Terms at any time by posting the revised version on the Site and updating the “Last updated” date. Changes are effective when posted. Your continued access to the Site or purchase or use of any Product after changes are posted constitutes your acceptance of the revised Terms. We may also modify, suspend, or discontinue any part of the Site or any Product at any time without notice or liability.
23. Assignment
You may not assign or transfer these Terms or any rights or obligations under them without our prior written consent. We may freely assign or transfer these Terms, in whole or in part, without restriction. These Terms bind and benefit the parties and their permitted successors and assigns.
24. Severability, Waiver & Entire Agreement
If any provision of these Terms is held invalid, unlawful, or unenforceable, that provision shall be modified to the minimum extent necessary to make it enforceable, or if it cannot be so modified, severed, and the remaining provisions shall continue in full force and effect. Our failure to enforce any provision is not a waiver of our right to do so later. These Terms, together with the Privacy Policy and any additional terms or policies expressly incorporated by reference, constitute the entire agreement between you and Sergg regarding the Site and the Products and supersede all prior or contemporaneous understandings. Section headings are for convenience only and do not affect interpretation. These Terms do not create any third-party beneficiary rights except for the indemnified parties named above.
25. Contact
Questions about these Terms may be directed to Sergg Device through the contact information provided on the Site’s Contact page.
These Terms are provided for general purposes and do not constitute legal advice. The provisions above apply only to the extent permitted by applicable law; where any provision is restricted or prohibited by the law of your jurisdiction, it applies only to the maximum extent the law allows, and your non-waivable statutory rights remain unaffected.

The Sergg Labs Guide
A Perfect Fit, Whatever Your Size
Sergg is engineered for every man — big or small. The system is two cylinders and three interchangeable threaded adapters. With Adapter 1 installed, Cylinder 225 gives you 7″ of internal length by Ø2.25″, and Cylinder XL225 a full 10″ by the same Ø2.25″ — each measured with Adapter 1 fitted, and shorter without it. Adapters 2 and 3 thread in with angled entrances that add roughly 1″ and 2″ of internal length — and every combination locks together leak-proof. The Fit Lab below starts on Adapter 1 — switch adapters inside it to size the whole system.
Dial in your measurements
Two sliders, one live blueprint. Watch your numbers take their place inside the chamber — clearance, bore, and all.
With Adapter 1 installed: 7″ of internal length by a Ø2.25″ bore. Most men under 6″ live here comfortably. Elasticity differs man to man — if you measure near 6″ and expand strongly under vacuum, the XL225 removes the question.
Shop Cylinder 225With Adapter 1 installed: a full 10″ of internal length by the same Ø2.25″ bore. Built for longer men — and for anyone whose tissue expands powerfully under vacuum — with room to grow and never meet the end.
Shop Cylinder XL225One Cylinder. Three Entrances. Four Directions.
Every pump in history has been a straight tube. Sergg is the first with an interchangeable, angled entrance — the invention the patent protects. Pick an adapter, thread it in, and clock it to any of four directions. Watch how it goes together.
Watch it come together
One cylinder, three adapters, four directions. Watch the patented joint thread in, seal, and clock — exactly as it will in your hands.
Sergg is a pleasure device; any engorgement effects are temporary. Not a medical device.
How To Measure
For the most accurate fit, measure when fully erect. For length, press a ruler gently to the base and measure along the top to the tip. For girth, wrap a soft tape measure or a strip of string around the thickest part, then measure it against a ruler. Enter your length and girth into the Fit Lab above to see your recommended chamber.
A note on elasticity. Cylinder 225 runs 7″ deep with Adapter 1, and erect tissue is wonderfully elastic — how much it lengthens under vacuum is simply different on every man. A man measuring 6″ can absolutely use the 225: a generous expander will fill it like it was made for him, while another man at the same 6″ keeps comfortable breathing room — both are winning. The Fit Lab simply leans toward the Cylinder XL225 the closer you get to 6″, because its 10″ of internal length hands a strong expander unlimited road.
Still unsure? Our discreet support team is glad to help you choose — just reach out.
What Science Actually Says About Size
Most men quietly believe the average erect length is six inches. The largest clinical review ever conducted — 15,521 men, measured by health professionals and published in BJU International — says otherwise. The real numbers are friendlier than the locker-room legend.
A few more truths worth knowing. The average flaccid length is about 3.6″ — and flaccid size is a famously poor predictor of erect size, so the man you are at rest says little about the man you become. Perception research found that most men overestimate the average by nearly an inch, which means a great many men walking around feeling “below average” are, in fact, standing right on it — or above. And partners? In one study, 85% of women reported being satisfied with their partner’s size; in another, 77% said length was unimportant to them.
That is why the Fit Lab’s average marker sits at 5.16″. If your number is anywhere near it, you are not small — you are the standard the world was measured against. And whatever your number, there is a Sergg cylinder machined for it.
