Threaded Mechanical Tee
Style 3J Threaded Outlet Mechanical Tee
1.Product introduction:
Mechanical tees help you retrofit and expand sprinkler systems
The Mechanical Tees provide a fast and easy mid-pipe threaded branch outlet. The mechanical tee utilizes ductile iron housings, a grade E moulded gasket and heat-treated carbon steel track bolts and nuts. UL/FM working pressure of Model 7721 rated to 300 psi (20 bar) Threads are NPT per ANSI B1.20.1 or BSPT per ISO 7. UL/FM working pressure is 20 bar (300 psi).
●By using the bolting method the branch pipe is directly connected with the main pipe without welding.
●All products have 21.3mm(1/2’’)outlets and 26.9mm(3/4’’)outlet.All sizes is the sasme with 33.4mm(1’’)outlets
●Enhanced body resists 4 times working pressure.
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. This eliminates the need to cut or disassemble pipe, potentially reducing man-hours and materials costs for something like the installation of a simple branch line.
