Male Branch Tees are very similar to traditional Straight Pipe Tees where they are used to connect pipelines with another pipe of the same size at a right angle with the line. The difference is these Male Branch Tees feature a male thread on the branch allowing a female pipe thread to be connected at 90°

A merchant coupling is a fitting used to join pipes, of similar size, together in a straight-line run. Merchant steel fittings are designed with Dryseal Taper Threads (NPTF) for more critical applications. NPTF Dryseal threads produce a mechanical seal by the mating and slight crushing of the threads when a wrench is applied to tighten the fittings. Half Merchant Couplings are about half the length of Full Merchant Couplings.

Pipe Unions are a type of a fitting designed to unite two pipes of the same size so they can be detached without causing any deformation to the pipes.
