Product details

An assembly of mechanical tees is assembled around the pipe, positioning the collar inside the hole and enclosing a rubber gasket designed to fit the particular piping system. By fastening the bolts, the branch becomes more secure. A mechanical tee is used to connect piping directly to a system.

Product Overview

This mechanical Tee ASTM A536 GR x Thread（MECH TEE) is used for branch line connection on main grooved pipelines in fire protection, water supply and industrial piping systems. It enables on-site tapping and branch installation without cutting the main pipe, featuring convenient construction and reliable sealing. Made of high-strength ductile iron, it provides good pressure resistance and long service life.
