Spirax-Sarco 0680762 TD42L Thermo-Dynamic Steam Trap

The Spirax-Sarco 0680762 TD42L Low Capacity Thermo-Dynamic Steam Trap is a 1/2 in nominal, FNPT-connected thermodynamic trap designed to discharge condensate very close to the steam temperature, preserving energy in small steam lines while helping prevent water hammer. As the low-capacity member of Spirax Sarco’s TD42 family, it offers a compact, maintainable solution for moderate condensate loads. The unit features a cast iron body with a stainless steel disc and an integral seat design with seating surfaces finished in ENP, providing durable sealing under fluctuating condensate conditions. It is rated for temperatures up to 752°F (400°C) and pressures up to 63 bar (914 psi), making it suitable for typical boiler and steam-distribution applications where precise condensate drainage is required without excessive steam loss. Ideal for small to mid-size applications such as heating coils, process heat exchangers, and steam headers, this trap minimizes energy waste while ensuring reliable condensate removal across varying operating conditions.
