Kohler 42038 Cold Plunger

Product Description

The KOHLER 42038 is a cold plunger designed for use in faucet and valve assemblies where a dedicated cold-water stem component is required. This small but essential part controls the flow of cold water through the valve body, maintaining proper seating and shutoff function within the fixture. Licensed plumbers and experienced fixture technicians install this type of component during routine faucet rebuilds or when diagnosing drips and improper shutoff caused by worn internal valve parts. At 0.025 pounds, it is a lightweight precision replacement piece suited to detailed repair work.

This plunger is suited to residential and light commercial plumbing applications where KOHLER faucet or valve assemblies require internal repair. It is typically installed during a stem rebuild or full cartridge-and-seat service on a cold-side valve. Plumbers working on single-handle or two-handle faucet configurations will encounter this type of component when restoring proper cold-water control to a fixture showing signs of drip or failure to seat.
