Equal coupling black malleable iron

Black cast iron female/female equal coupling plumbing fitting.

This black cast iron Female/Female equal coupling allows threaded fittings or threaded pipes of the same size to be easily connected by screwing; it is particularly useful for joining two pipes together and thus extending their length. It is compatible with all black cast iron or galvanized fittings and black steel or galvanized threaded pipes of the same size sold in our online shop. The parts simply screw together, without welding, to make strong assemblies easily.

Description of the female/female equal coupling:

The equal coupling has two female ends (tapped) of the same size. Its shape makes it easy to screw on using an adjustable spanner.
