Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Zurn's four-part spud escutcheon and coupling assembly (Part no. P6003-H) is designed to fit AquaVantage and Aquaflush flush valves. Its metal parts, the ¾-inch spud nut and escutcheon, are constructed of cast brass with a chrome-plated finish. Its soft parts, the gasket and washer, are 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.
