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.

Faucet compression valves fit compatible compression-style faucets to create a tight seal that prevent leaks.

Faucet flow-control valves reduce water use without cutting water pressure. They install at the hot and cold supply lines to decrease water flow while maintaining pressure. They're commonly used in hotels, hospitals, multiunit dwellings, and public buildings.

These kits include parts for repairing a faucet's vacuum breaker, which stops water backflow to prevent contamination of the water supply.

Faucet solenoid valves activate water flow in sensor-operated faucets. They stay closed to stop flow until they are triggered by the faucet's proximity sensor. These valves are commonly used to replace valves that fail to turn off water flow.

Thermostatic mixing valves sense water temperatures and adjust the flow from hot and cold water lines to match the faucet settings. They help prevent scalding by maintaining a constant water temperature even as the water volume changes. They're typically found in faucets with separate water volume and temperature controls. These valves are used as replacements for valves that allow leaks from a spout and no longer control water temperature or volume.

Faucet diverter valves redirect water from a spout to a spray head. These valves are used as replacements for valves that restrict water flow or no longer allow water to be diverted.

Faucet valve parts replace worn or broken valves and valve parts to repair leaks and restore proper water flow and pressure.
