Bradley s65-253 Piston Liner Kit Tmv

Product Description

The BRADLEY s65-253 is a piston liner kit designed for use with Bradley thermostatic mixing valves (TMV). This internal service kit provides the piston liner component required to rebuild or restore proper mixing valve function. Thermostatic mixing valves regulate hot and cold water to deliver a safe, controlled outlet temperature, making this type of kit essential for maintaining compliant and reliable tempering valve performance. The s65-253 is a manufacturer-sourced replacement part intended for installation by licensed plumbers performing routine valve maintenance or emergency service.

This piston liner kit is used during the service and rebuild of Bradley thermostatic mixing valves in commercial and institutional plumbing systems. Typical applications include emergency eyewash stations, lavatory tempering assemblies, and other Bradley TMV installations where the internal piston liner has worn or failed. Restoring the piston liner returns the valve to proper thermostatic operation and helps maintain code-compliant outlet temperatures.
