Oatey PP85560 Sink Strainer Washer Coupling

Product Description

The OATEY PP85560 is a brass and cloth-reinforced rubber washer coupling designed for use with sink strainer assemblies. Measuring 1-3/4 inches outer diameter, 1-3/8 inches inner diameter, and 1/8 inch thick, this washer seats between the strainer body and the sink basin to create a watertight seal. It is a standard replacement component installed by licensed plumbers and experienced DIYers during sink strainer service or new installations. The cloth reinforcement adds dimensional stability and helps the washer resist compression set over time.

This washer coupling is used in residential and light commercial plumbing applications wherever a standard sink strainer requires a sealing washer. It is sold individually and is a direct replacement part for routine maintenance and repair work on kitchen or utility sink drain assemblies.

Compatibility

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer as part of a sink strainer replacement or repair. Shut off the water supply and clear standing water from the sink before beginning work. Seat the washer evenly against the underside of the sink basin before tightening the strainer locknut to avoid uneven compression. Do not overtighten the locknut, as this can deform the washer and compromise the seal.
