The Ultimate Gel Ring is one of the top-performing vacuum therapy penis pump accessories, providing user comfort and effective tension. It's 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 larger ring while still maintaining adequate firmness. The solid tabbed-style handles are easy to grip when loading and give the ring greater durability.
