Brass: Not Rated
Bronze: 235 psi @ 400° F
Temp. Range:
Brass: 35° to 350° F
Bronze: -20° to 400° F

Strainers catch debris in your pipeline, preventing damage to valves, pumps, nozzles, and other sensitive equipment. They are designed for medium-pressure applications. Strainers have a threaded drain with a plug that provides access to the screen without disconnecting your line. They have good corrosion resistance.

Strainers for use with drinking water meet NSF/ANSI 61 safety standards for drinking water systems.

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.
