Application

Thermostatic steam traps are critical components in hydronic and steam heating systems, removing condensate and air while retaining live steam. Over time, the diaphragm seat can wear or fail, leading to inefficient trap operation. Replacing the diaphragm seat with the Watts 0036859 is a cost-effective alternative to full trap replacement, helping maintain system efficiency and reducing downtime.
