20Pack Tailpiece O-Ring Seal Kit Compatible with Sloan Flush Valves

Key features

• Part Number and Size: Flushometer tailpiece O-ring with 1-1/8 in inner diameter, designed for stop tail sealing applications. Replaces H-553, H553, and 5308696, and cross-references P6000-C31 and A912809-0070A for listed commercial flushometer tailpiece and control stop connections.
• Complete Compatibility: Compatible with Sloan Royal and compatible with Sloan Regal flushometer tailpiece applications using H-553 / H553 / 5308696. Also compatible with Sloan Optima tailpiece applications using the same H-553 / 5308696 O-ring style. Also compatible with Zurn AquaVantage and compatible with Zurn AquaFlush flush valve tailpiece applications using P6000-C31, and compatible with American Standard adjustable tailpiece applications using A912809-0070A.
• Premium Nitrile Rubber: Made from premium nitrile rubber for commercial restroom plumbing service. The material helps resist water exposure, common restroom cleaning chemicals, compression deformation, and repeated flush cycles, helping the O-ring maintain sealing contact inside the tailpiece groove.
• Tailpiece Seal Location: Installs in the groove on the flushometer tailpiece. When the tailpiece slides into the control stop, this O-ring forms the sealing surface at the joint, helping reduce water seepage around the control stop and tailpiece connection on toilets and urinals.
• Maintenance Use: Suitable for replacing worn, flattened, dried, cracked, or stretched tailpiece O-rings during flushometer repair, control stop service, valve maintenance, or restroom upkeep. Not intended for vacuum breaker, spud gasket, diaphragm, handle seal, or other gasket locations that require different sizes.
• [Usage Scenarios] Intended for commercial and institutional restrooms using flushometers compatible with Sloan Royal / Regal, Zurn and American Standard where water seeps from the control stop / tailpiece connection. A quick O-ring change at this location often stops common drips on urinals and toilets, making these NBR O-rings useful for plumbers and maintenance teams who replace a tailpiece seal on nearly every flushometer repair. Not for vacuum breaker, spud or other gasket locations that require different sizes.
