Mechanical tees, as part of grooved piping systems, use gaskets secured by housings to attach a new line of pipe to an existing one. The mechanical force from the bolts and nuts combined with the gasket and lubricant creates a tight seal around a hole drilled into a run of pipe.

A grooved piping system is a method of joining pipes using grooved couplings rather than welding, flanging, or threading.

The groove-type pipe fitting only needs to install the standard parts supplied, and does not need welding and galvanizing, so the installation speed is significantly faster than the screw connection and flange connection
