MECHANICAL TEE (THREAD)Model 402 MECHANICAL TEES

MECHANICAL TEEThe Lede 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 loca�on. The mechanical tee is then posi�oned so that the built-in loca�ng collar ts within the hole. As the housing bolts are �ghtened the pressure moulded gasket forms a leak-�ght seal. Use of the Lede mechanical tee can eliminate the need for mul�ple couplings and �ngs.

Caution: Piping prac�ces require that main and branch connec�ons are at a true 90° angle. Also be certain that the loca�ng collar is securely posi�oned inside the outlet hole before �ghtening the housing. When mechanical tees or mechanical crosses are used as transi�on pieces between two runs, the tees or crosses shall be assembled prior to making the branch connec�ons.

Lede offers a full range of mechanical tees:Model XGQT04: Threaded outlet, NPT or BSPT (ISO 7-1)

pipe threadsModel XGQT04G: Cut-grooved outlet (machined)Model L922 and 041: Saddle-Let; Small mechanical tee

with threaded outlet, NPT or BSPT (ISO 7-1) pipe threads

MODEL 041 SADDLE-LET ( U bolt Mechanical Tee)

The Model 041 Saddle-Lets is the ideal outlet �ng for direct connec�ons to sprinkler heads, drop nipples and or gauges. No need for welding, just cut or drill a hole at the desired outlet loca�on. Posi�on the Saddle-Let so that the loca�ng collar ts within the hole and secure with the U-bolt and nuts. The Saddle-Let comes with a standard black nish or as an op�on can be supplied electro zinc plated or painted orange. The Saddle-Let allows full bore ow and is pressure rates to 300 psi (20 bar).
