STERIS P129359-276 Thermostatic Steam Trap 3/4″ – 4205

The STERIS P129359-276 is a thermostatic steam trap in the 4205 series with a 3/4" connection. Steam traps are used in sterilizer systems to automatically discharge condensate and air while preventing live steam loss. This model is typically found in STERIS autoclave and sterilization equipment where it manages condensate removal from steam lines and chambers. Thermostatic traps operate by sensing temperature differential; as condensate cools below saturation temperature, the trap opens to discharge it. The 4205 series is a replacement and service part for STERIS sterilization systems.
