Tapco 974-336 Single Handle Faucet Cartridge

Product Description

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.
