Installation Instruction For Threaded &Grooved Mechanical Tee





1.Take out the Rigid &Flexible Coupling Clean the gasket sealing surface within 16mm of the hole and visually inspect the sealing surface for defects that may prevent proper sealing of the gasket.Don't drill the hole on weld line.	2.Split the Rigid &Flexible Coupling If any burrs or slug exists at the pipe hole,please remove them before assembly,to protect the gasket and avoid leakage.	3.Pipe preparation Insert the gasket into outlet housing making sure the tab in the gasket line up with the tab recesses in the housing.Align outlet housing over the pipe hole making sure that the locating collar is in the pipe hole.	4.Lubricate gasket Align the strap around the pipe,inser the bolts and tighten the nuts finger tight.




5.Gasket installation Alternatively and evenly tighten the nuts to the specified bolt torque.	6.Housing installation There should be even gaps on two sides between upper and lower housings.
