The primary purpose of a Tee is to make a 90° branch from the main run of pipe. Standard, there are 2 possibilities, on behalf of the equal tee and reducing tee. The equal tee (or straight tee) is used as the branch has the same diameter as the run-pipe. The reducing tee is used as the branch has a smaller diameter than the run-pipe.
