Torque Specifications
Measurements are made with lubricated components and a certified calibrated torque wrench.
Inconsistencies in wrench settings, lubrication and technique may not produce a leak free seal. If
leakage occurs, the torque can be increased to seal the components. However, do not exceed the
recommended torque value by more than 15 percent. If leakage persists, there is a component
problem.
Excessive torque can cause component damage or failure, resulting in potential
hazards to equipment and personnel.
