It is designed with three openings, allowing for the connection of three pipes at a 90-degree angle. It is mainly used to change the direction of fluid and is used at the branch of the main pipeline. It can be classified according to the size of the pipe diameter.
Youfa brand Tees are made of materials such as carbon steel, cast steel, and stainless steel.
Which steel materials do you need ?There are various types of fitting tees, including equal tee (where all three openings are of the same size), reducing tee (where one or more of the openings are of a different size), and lateral tee (which has a 45-degree branch connection).
