Installation Instructions
Step 4
Position Bushings
Insert bushings into fitting body. A small amount of resistance indicates the bushings
are being compressed to further capture the jacket. Note: The piloting feature
of the bushings ensures the tubing is aligned properly with the fitting body for
a uniform flare and a gas tight seal.

Step 5
Wrench Fitting
Slide nut over bushings and thread onto fitting body. Some resistance will be
experienced as the nut begins to compress the tubing and create the double wall
flare.
Continue to thread the nut until resistance to wrenching increases greatly and the
double wall flare is tightly seated.
Note: During the tightening process rotate the nut only, do not rotate the fitting
body. For recommended torque values refer to the table below.

Termination Fitting
1. Remove flange from brass fitting assembly.
2. Slide flange over tubing.
3. Attach brass fitting to tubing. (steps 2 - 5)
4. Thread flange back onto fitting assembly.
5. Mount completed termination assembly.
