A pipe tee is also called triplet, three way and "T" pieces and it can be used to either combine or split a fluid flow. Most common are tees with the same inlet and outlet sizes, but 'reducing' tees are available as well.

A pipe tee is a type of pipe fitting which is T-shaped, having two outlets at 90° to the connection to the main line.

Reducing tee

A reducing tee has a branch that is smaller than the main run, allowing for branching off to a smaller pipe or equipment from the main run.

Equal tees

Equal tee (or straight tee), means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.

Lateral Tee

A Lateral pipe tee means a pipe fitting which is similar to a tee but has a side opening outlet branch at a 45 degree angle.

Barred Tee

A barred tee is a tee or any fitting with a branch used in pipelines that are pigged and has a restriction bar welded internally, preventing the pig from traveling down a branch connection.
