What Is an Iron Pipe Thread Adapter?
Iron pipe fittings are commonly used threaded fittings, generally made of electroplated iron.
Iron adapters are used in chemical, petroleum, natural gas, and other industrial piping applications. Their corrosion resistance and high-temperature performance help support system safety and reliability.
Iron Pipe Thread Adapter Applications
Adapters connect equipment and threaded fittings for gas or liquid piping. They also convert between different fitting types, sizes, and thread specifications.
Designed for piping systems, equipment assembly, liquid piping, air piping, and gas piping.
