Abstract
Abstract A replacement valve assembly with an adjustable sleeve fitting received in the valve port of a conventional faucet body and sealed by a locking nut and gasket. A valve stem is disposed centrally through the fitting and carries a frictionless washer retainer to bias a washer to the valve seat and to freely swivel on the valve stem to reduce wear. An adjustable bushing with an associated jam nut biases a sealing gasket to the valve stem.
