Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Designed to fit AquaVantage and Aquaflush diaphragm flush valves, Zurn's replacement molded diaphragm disc (Part no. P6000-E14) is made with our chemical-resistant GO BLUE material. GO BLUE parts last up to 10x longer than the competitors', reducing maintenance costs and extending their lifespan. Zurn flush valve replacement parts and retrofit kits can be used to upgrade any diaphragm flush valve and are interchangeable with Sloan flush valves. When you need a replacement part for repair or maintenance of a flush valve, trust Zurn for genuine, reliable parts. Material: Rubber.
