Ts Brass 003164-45 Rubber Spring Check Plunger Nsf 61

Product Description

The TS BRASS 003164-45 is a rubber spring check plunger designed for use in cartridges equipped with spring check assemblies. The plunger includes a seat disc and spring check seat washer, providing a reliable sealing surface that prevents backflow within the cartridge. This component is certified to NSF 61 Section 9 and NSF 372, confirming compliance with drinking water system component standards and lead-free material requirements. It is typically installed by licensed plumbers during cartridge maintenance, repair, or rebuild of faucet and mixing valve assemblies.

This part is suited for commercial and residential plumbing applications where spring check cartridges are used to control flow direction. It is used in repair and rebuild scenarios where the existing rubber check plunger has worn, deformed, or lost its sealing capacity. The NSF 61 and NSF 372 certifications make it appropriate for potable water service.
