This coupling pipe fitting is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability.

It can connect two pipes going in the same direction with the same diameter to extend a straight run and has female NPT threads for connecting to male threaded pipes, creating that tighter seal than other straight threads.
