Timm Medical Tension Rings & Vacuum Therapy Accessories

Timm Medical is a longstanding name in vacuum erection device (VED) therapy, a non-invasive, drug-free approach to managing erectile dysfunction. This collection focuses on the tension rings that complete that system — the constriction bands worn at the base to maintain rigidity once the vacuum has done its work. Getting the ring right matters more than most first-time buyers expect: too tight is uncomfortable and unnecessary, too loose won't hold, and tension needs often change over time.

That's why our selection spans a range of tension levels and internal diameters. The Pos-T-Vac Mach Ring is available in low tension (Size #8, made with a soft, flexible gel for comfortable everyday use) and standard tension (Size #7), giving you room to fine-tune fit and hold. The Pos-T-Vac Ultimate II Round Ring in medium, high tension suits those who need firmer constriction, while the Max Elasticity Tension Ring, Size D (3/4-inch ID, low tension) stretches easily for a gentler, forgiving fit and simpler application.

Two questions come up again and again. First, which tension? Many users start low and step up only if rigidity isn't maintained — low-tension gel rings like the Mach #8 are a common, comfortable starting point. Second, which size? Internal diameter should match your anatomy, not guesswork; the labeled ID (for example, the 3/4-inch Size D) is your guide, and having a couple of options on hand lets you compare comfort directly. These rings are compatible with Timm Medical Pos-T-Vac vacuum systems and are designed for repeat use with proper cleaning between sessions.

Timm Medical rings are a discreet, reusable component of a therapy option that avoids medications and their interactions — an appealing route for men who can't or prefer not to use oral treatments.
