Coupling Reducing – Malleable Black Iron

Black Malleable Iron Reducer Coupling with two female-threaded connections. This fitting allows the user to connect (or couple) two different-sized pipelines. It is ideal for extending a pipe to reach another section of the system with a different-sized pipe. Installation is very simple , as it does not require any welding or soldering. An inexpensive thread sealant will be required for a water tight seal. Black iron is resistant to pressure, heat, and corrosion, so it is most often found in gas and oil systems.
