About Duct Connections

Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Galvanized steel has good corrosion resistance. 304 stainless steel is more corrosion resistant than steel and aluminum.

Chemical-Resistant Duct and Fittings
Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes. Use PVC pipe cement (not included) to secure components. Fittings have female ends with a slightly larger diameter to press-fit over duct.

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.
