7.Installation Instruction for U-Bolt Mechanical Tee

1. Pipe Preparation
Clean the gasket sealing surface within 16mm of the hole and inspect the sealing surface visually for defects that may prevent proper sealing of the gasket. Don't drill the hole on weld line.
2. Remove burrs
Remove any burrs or slug before installation to protect the gasket and prevent leakage.
3. Gasket&Housing Installation
Insert the gasket into outlet housing properly. Align outlet housing over the pipe hole making sure that the locating collar is in the pipe hole.
4. Alignment

Attach the U-bolt from the other side and tighten the nuts.
5. Tighten nuts
Alternatively and evenly tighten the nuts to the specified bolt torque.
6. Installation complete
Proper torquing of bolts is required to obtain specified performance.
-Over torquing the bolts may result in damage to the bolt and/or casting which could result in pipe joint separation.
-Under Torquing the bolts may result in lower pressure retention capabilities, lower bend load capabilities, joint leakage and pipe joint separation. Pipe joint separation may result in significant property damage and serious injury.
