The prefabricated direct buried tees refer to tees for main pipes, branch pipe fittings, and pipe joints. Reducing tee is a kind of tee. The tee has a common equal tee and a reducing tee. How to connect prefabricated buried tees?

After tightening the nut, the specific pressure on the surface of the washer reaches a certain value, then it deforms and fills up the unevenness on the sealing surface, making the joint tighten. Flange joints are removable joints.
