Xylem-Hoffman Specialty 404222 1-1/4″ NPT 30 PSI Series H Cast Iron F&T Steam Trap

Description

The Xylem-Hoffman Specialty 404222 is a Series H Cast Iron Float & Thermostatic (F&T) Steam Trap engineered for reliable, continuous condensate discharge in low- to medium-pressure steam systems. With a 1-1/4″ NPT connection and a 30 PSI maximum operating pressure, this trap is well-suited for a wide range of commercial and industrial hydronic heating and steam distribution applications.

The float-and-thermostatic design combines two proven mechanisms in a single compact body: a float valve that continuously discharges condensate as it forms, and an integral thermostatic air vent that automatically purges non-condensable gases and air from the system. This dual-action operation helps maximize heat transfer efficiency, reduces system warm-up time, and protects equipment from air binding and water hammer.
