Danco 38802B Faucet Washer, 3/8 in ID x 5/8 in OD Dia, 1/2 in Thick, Rubber

The Danco cone washer is designed to be used for toilet or sink supply repair. The washer creates a leak-proof seal at the water supply inlet. It is designed for use on faucets, sinks and toilet ball cocks. Replacing a worn washer is an easy DIY project. New washers eliminate leaks, which waste both water and energy and can damage floors.
