Equal tee

A threaded equal tee is a three-opening fitting that creates a branch and whose product identity defines an equal nominal-size relationship between run and branch. This distinguishes it from a reducing tee, but does not establish thread form, material, coating, or male and female opening arrangement. Unlike an elbow, it introduces an additional branch path. Selection should review the size and arrangement of all three connections, branch direction and load, flow distribution, thread-sealing method, assembly space, and maintenance access against the project drawing and piping specification.
