Pos-T-Vac Mach Support Ring | Penis Pump Accessories

Product Description

The Pos-T-Vac Mach Support Ring is a premium vacuum therapy penis pump accessory that provides user comfort and effective tension. This support ring is 30% thicker than Pos-T-Vac's basic support ring styles. This thickness in the center of the ring helps produce tension that is dispersed over a wider area, allowing the user to wear a large-size ring while still being able to maintain adequate firmness. The Mach Support Ring features looped handles that are designed for easy loading, allowing users to guide the support ring over the loading cone and onto the penile tube.

  1. Effective but hard to install 4 Star Review

    They are very stiff, which makes for a good erection once you get it on your penis; but unfortunately, they are very difficult to get fitted on the pump tube, even with the special tool I previously purchased.

  2. Confidence 5 Star Review

    Knowing for sure that you can perform is wonderful thing. You can always rely on the vacuum pump and ring to achieve a full erection very time. It provides peace of mind and makes lovemaking fun again.
