125 MINSTAC - Fitting Torque Limits

NOTE:
Excess torque will cause the ferrule to crush restricting the flow through the fitting.

Minimum recommended torque: 7 ozf•in (0.05 N-m)
Maximum recommended torque: 21 ozf•in (0.15 N-cm)


Coupling Installation Tools
TTTA6202227A - Torque Wrench


TTTA6200227C - Wrench


Procedure:
    1. Start threading the fitting assembly into the 125 MINSTAC fitting boss by hand.
    2. Tighten the fitting between 7 to 21 ozf•in (0.05 to 0.15 N-m) by slipping the Lee Torque Wrench TTTA6202227A onto the hex of the Coupling Screw.
    3. The minimum torque is achieved by pressing the shorter torque arm clockwise until it just contacts the longer arm. To check that maximum recommended torque is not exceeded, invert the Torque Wrench and press the longer torque arm clockwise until the Coupling Screw begins to move. This should occur before the torque arms make contact. After gaining a feel for the proper torque, use of the Torque Wrench may be discontinued.
