Chicago Faucets 377-XTRHBL12JKABNF 12 pack

Faucet cartridges control the flow of water from cartridge-style faucets. They seal and unseal water inlet ports to stop and start water flow and adjust pressure and temperature. Their cylindrical base has discs or openings that regulate flow as faucet handles are turned on and off. These cartridges are commonly used as replacement parts in leaking or dripping faucets.
