These Danco faucet washers can help you repair your leaky faucet. Replacing the seals on the faucet stem will create a better seal and help prevent water leaks. Faucets usually have one or more o-rings that prevent water from leaking out around the spout. Replacing worn-out o-rings is an inexpensive alternative to replacing the entire faucet fixture. Stopping the leak saves both water and energy. This O-Ring Assortment fits Cuthbert, Delta-Delex, Valley, Wallaceburg and Waltec faucets and has a 13/16 in. OD x 11/16 in. ID x 1/16 in. wall thickness. Color: Black.
