The TAPCO 974-336 is a replacement faucet cartridge designed for single-handle lavatory and kitchen faucet applications. The cartridge serves as the internal valve mechanism that controls water flow and temperature mixing within the faucet body. This part is typically installed by licensed plumbers or experienced service technicians during routine faucet repair or rebuild service. Replacing a worn or failed cartridge restores proper shutoff and temperature control without requiring a full faucet replacement.
The 974-336 is suited for residential lavatory and kitchen sink faucet repairs. It is used when a single-handle faucet exhibits symptoms such as dripping, difficult handle operation, or loss of temperature control. The cartridge drops into the faucet body as an OEM-style replacement, making it a practical choice for service calls requiring fast, reliable component-level repair.
Designed as an OEM-style replacement cartridge for single-handle lavatory and kitchen faucets. Consult the faucet manufacturer documentation or cross-reference the original part number to confirm fitment before installation.
Installation is typically performed by a licensed plumber. Shut off the water supply to the faucet at the angle stop or main shutoff before beginning disassembly. Depressurize the line by opening the faucet handle after shutoff. Follow local plumbing codes and the faucet manufacturer service instructions when seating and securing the replacement cartridge.
