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°

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.
