Mechanical Tee

The asiajoint hole-cut mechanical tee provides a fast and easy mid-point branch outlet without welding. First a hole is cut or drilled at the desired outlet location. The mechanical tee is then positioned so that the built-in locating collar fits within the hole. As the housing bolts are tightened the pressure moulded gasket forms a leak-tight seal. Use of the asiajoint mechanical tee can eliminate the need for multiple couplings and fittings.

asiajoint offers a full line of mechanical tees:
Model 7721: Threaded outlet, BS21 (ISO-7) or NPT pipe threads Model 7722: Cut-grooved outlet Model 723 : Saddle-Let; Small mechanical tee with threaded outlet, BS21 (ISO-7) or NPT pipe threads

Mechanical Cross

A mechanical cross connection can be made by combining two mechanical tee upper housing segments. While the housing segments must be the same size the branch outlets can be of the same or differing sizes or configurations.

Bolt Fastening Torque For Mechanical Tees & Crosses, #7721/#7722

All mechanical tees and crosses are designed with a gap between the bolt pads. Do not attempt to bring the bolt pads together (metal-to-metal) when tightening the housings. Excessive torque may result in joint failure. See the recommended bolt fastening torque
