Oatey PP83551 Flush Valve Shank Washer

Product Description

The OATEY PP83551 is a fit-all flush valve shank washer designed to seal the shank connection on flush valve assemblies in toilet and urinal installations. The washer measures 2-1/4 inches inner diameter by 2-7/9 inches outer diameter, providing a reliable compression seal between the flush valve shank and the fixture or tank. Plumbers and service technicians use this washer when replacing or reseating flush valves to stop leaks at the shank fitting. It is sold individually and ships one per card, making it a straightforward single-unit repair part for residential and light commercial plumbing service calls.

This washer is suited for flush valve shank replacement and retrofit work in both residential bathrooms and commercial restroom facilities. It is a standard fit-all design intended to work across a range of flush valve configurations where the shank requires a seated rubber or composition seal. Plumbers typically carry this part as a stock replacement item when servicing older or worn flush valve assemblies.

Seat the washer evenly on the shank before tightening the locknut to avoid uneven compression and potential leaks. Work complies with applicable IPC and local plumbing code requirements.
