Danco 38809B Black Rubber Slip Joint Washer

Product Description

The DANCO 38809B is a molded cone-style rubber slip joint washer used in drain and waste plumbing connections. It creates a watertight seal at slip joint fittings by compressing between mating surfaces when the slip nut is tightened. Sized at 27/32 inches by 9/32 inches, this washer is made from black rubber and is sold individually. Plumbers and experienced DIYers install this type of washer when servicing or replacing P-traps, sink drain assemblies, and similar slip joint drain components.

This washer is commonly used in residential and light commercial plumbing applications where standard slip joint drain connections are present. Typical install locations include kitchen and bathroom sink P-traps, drain extension tubes, and other slip joint drain fittings. The molded cone profile ensures proper seating and a leak-free connection when correctly installed. It is packaged individually in a UPC-coded bag for single-use replacement service calls.

Installation Notes

Installation is performed by licensed plumbers or qualified DIYers during drain assembly service. Shut off water supply and clear standing water from the drain before disassembly. Seat the washer fully into the fitting before hand-tightening the slip nut, then snug with channel-lock pliers — do not overtighten, as excess force can distort the rubber and cause leaks. Verify no drips are present after restoring flow.
