Pos-T-Vac Tension Rings & Erectile Dysfunction Aids

Pos-T-Vac from Timm Medical is a long-trusted name in vacuum therapy for erectile dysfunction—a drug-free, non-invasive approach many men choose to preserve intimacy and penile health. This collection focuses on the constriction (tension) rings that complete a vacuum erection device system, holding an erection once it's achieved. Because these are the components that come into direct contact and wear over time, having the right size and tension on hand matters for both comfort and reliability.

Tension rings are not one-size-fits-all. Fit affects both how securely a ring maintains firmness and how comfortable it feels, so most men benefit from having a couple of sizes and tension levels to compare. Our range spans lighter and firmer options: the Pos-T-Vac Mach Ring #8 in low tension is made with a soft, flexible gel that's easy to apply and gentler on the skin—a sensible starting point if you're new to therapy or prefer a softer feel. The Mach Ring in standard tension (#7) offers a middle-ground hold for everyday use, while the Ultimate II Round Ring, Medium, high tension provides a firmer grip for men who need more support to maintain rigidity.

A common question is how long a ring can safely stay in place—generally no longer than 30 minutes, and rings should be replaced periodically as the material naturally loses elasticity with repeated use. Keeping fresh rings in rotation keeps your system performing the way it did on day one.

These rings are designed to work with Pos-T-Vac vacuum devices. If you're building or resupplying a full system, browse Post-T-Vac Medical for related components, and explore compatible support products from A-T Surgical. Discreet packaging and shipping come standard on every order.
