Faucet parts and accessories replace broken components to keep faucets in good working order or modify faucets to suit specific applications. These parts typically fit specific faucet brands. Faucet cartridges, stems, valves, handles, and foot pedals provide control over water flow. Faucet escutcheons and cover plates conceal mounting holes and hardware. Faucet washers and O-rings seal against leaks. Faucet caps and index buttons keep water out of faucet handles and help set water temperature. Faucet spouts and sprayers direct water flow outward from the faucet. Faucet aerators help conserve water. Faucet sensor parts are used to repair faucets activated by proximity sensors.
