Repair your leaky faucet with the Danco 3J-4H/C hot/cold stem for Nibco and Streamway faucets. The hot and cold faucet is made from durable plastic. Replacing a faucet stem is an economical alternative to replacing the entire faucet. A leaky faucet wastes both water and energy. The installation of a new faucet stem and seat will stop the drip and return your faucet to like-new condition.
