Ao Smith 100210082 Tp Relief Valve Kit 3/4 in 150 Psi 210F

Product Description

The AO SMITH 100210082 is a temperature and pressure relief valve kit designed for residential and light commercial water heater installations. This kit provides a critical safety function by automatically releasing pressure or excess heat when either the temperature or pressure inside the tank exceeds safe operating limits. Rated at 150 psi and 210 degrees F, the valve features a 3/4 inch male inlet connection and a 4.75 inch cavity depth, making it a direct-fit replacement for standard water heater applications. Licensed plumbers and HVAC technicians install this component as part of routine service or water heater replacement work.

This TP valve kit is suited for use on residential tank-style water heaters where a 3/4 inch male-threaded port is present. The 4.75 inch cavity rating ensures proper probe immersion into the tank for accurate temperature sensing. It is a commonly required component during water heater commissioning or replacement to meet plumbing code requirements for pressure and thermal relief protection.
