Tapco 974-5319 Thermostatic Cartridge Price Pfister

Product Description

The TAPCO 974-5319 is a thermostatic cartridge designed as a direct replacement for Price Pfister faucet assemblies. Thermostatic cartridges regulate water temperature and flow by mixing hot and cold water supplies within the valve body. This cartridge fits into single-handle or thermostatic valve applications and is serviced by licensed plumbers during routine faucet repair, remodel work, or warranty replacement. It supersedes the earlier 974-321 cartridge, allowing technicians to source the current revision without cross-referencing legacy part numbers.

This cartridge is suited for residential and light commercial plumbing applications where a Price Pfister thermostatic faucet or valve requires cartridge replacement due to wear, leaking, or loss of temperature control. Typical install scenarios include bathroom lavatory faucets, shower valves, and tub-shower combination valves that use the Price Pfister thermostatic valve platform. Plumbers replacing cartridges during service calls or remodels will find this a direct drop-in for the superseded 974-321.
