Brass and Bronze Steam Traps

These steam traps have good corrosion resistance. Also known as thermostatic steam traps, they increase the efficiency of your radiator by venting cool air. Steam traps open and close based on temperature. They are often used with convection heaters, drip lines, and risers.

Steam traps with vertical pipeline orientation should be installed with the outlet pointing down.
