Danco 80330 Cone Washer, 3/8, 1/2 in Dia, Rubber, Orange

The Danco cone washer is designed to be used for toilet or sink supply repair. Cone washers are used to create a leak-proof seal at the water supply inlet. They are used on both faucets and toilet ballcocks. Replacing a worn washer is an easy DIY project. New washers eliminate leaks which waste both water and energy and can damage floors.
