Spirax-Sarco TSS-300 thermostatic steam trap, model TSS-300, is a compact 3/8" NPT steam trap designed to automatically drain condensate from small-diameter steam lines and heat-transfer equipment while minimizing live steam loss. It uses a temperature-sensitive element to open and discharge condensate when present, helping protect downstream equipment and improve energy efficiency in process heating systems. Ideal applications include steam coil heating jackets, small shell-and-tube or coil exchangers, and other compact steam-using installations where reliable condensate removal is required.
