This Danco Faucet Pull-Out Spray Hose connects the pull-out spray head to the faucet. It provides an upgrade over traditional vinyl hoses. It features a 3/8 in. diameter and included are quick connect adapter fittings that make for an easy installation. The kink resistant hose provides a quiet operation and its design will work with most faucet brands, but works best with most Moen, Delta and Oak Brook faucets that have a 1/4 inch threaded connection.
