Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Zurn’s O-Ring (Part no. P6000-C31) for use in the flush valve’s tailpiece works with AquaVantage® and AquaFlush® flush valves. Constructed with our chemical-resistant GO BLUE® material, this O-ring is built to last. 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 type flush valves. When you need a replacement part for repair or maintenance of a flush valve, trust Zurn for genuine, reliable parts.
