Streamlined Design for Drysuit DiversThe Dive Rite Low-Profile Balanced Relief Valve is engineered to provide maximum comfort and reliability during long or technical dives. As one of the thinnest and most compact drysuit relief valves available, it reduces drag, resists snagging, and offers a hands-free design that functions even when disconnected. This low-profile relief valve is ideal for divers who prioritize streamlined gear and minimal bulk.Precision Engineering with Leak PreventionThe valve features a balanced design with a one-way external mushroom valve that minimizes the risk of leaks by equalizing pressure between the tubing and drysuit interior. The Delrin body is durable, lightweight, and easy to clean with its coin-slotted outer cap. This balanced valve includes 24 inches of kink-free Norprene tubing, a swiveling hose barb for added comfort, a gasket for trilaminate drysuits, and a catheter adapter-everything needed for safe, dry, and comfortable diving.Note Installation requires a 1 5/8 inch or 41 mm punch and appropriate adhesive for your drysuit. Dive Rite recommends installation by a professional drysuit repair center. It is very important to clean your relief valve after use to prevent urinary infections. Steramine is a popular sanitizer for cleaning relief valves and rebreather breathing loops
