American Plumbing Partsmaster 8037 Mixet Stop Stems

Product Description

The American Plumbing Partsmaster 8037 is a pair of Mixet stop stems measuring 1.60 inches, designed as internal valve components for Mixet-style single-handle faucet and shower valve assemblies. Stop stems regulate water flow within the valve body, controlling both hot and cold supply sides. This replacement pair is installed by licensed plumbers and experienced service technicians performing faucet valve repairs or rebuilds. The 1.60-inch stem length is a critical fitment dimension, and selecting the correct size is essential for proper seating, shutoff performance, and leak-free operation.

Mixet-style single-handle valves are commonly found in residential bath and shower applications, particularly in older housing stock where original Mixet-brand or Mixet-compatible valves were installed. The 8037 stems are used during valve rebuild service calls when worn or damaged stems cause dripping, incomplete shutoff, or reduced flow control. Replacing stems in pairs ensures balanced wear and consistent performance across both the hot and cold sides of the valve assembly.

Inspect the valve seat and packing during service and replace as needed to ensure a leak-free repair. Installation must comply with applicable local plumbing codes and IPC guidelines.
