Re-Tightening Instructions

Step 1
Pic. 1 shows the fitting in the disconnected position. Insert the tubing with the pre-swaged ferrules into the fitting body making sure the front ferrule is firmly seated as shown in Pic. 2

Step 2
Finger-tighten the nut and then with a wrench turn the nut to the original 9 o’clock position. At this point a slight
change of resistance will be felt. Tighten the nut slightly more as the change in resistance is felt and the installation is complete as shown in Pic. 3 by tightening slightly more.

Superlok Tube Fittings Installation


Step 1
Insert the tubing into SUPERLOK Tube Fitting. At this
point, make sure that the tubing is in contact with the
shoulder of the fitting and then finger-tighten the nut.


Step 2
Before tightening the SUPERLOK nut, mark the starting
point at the 6 o'clock position.


Step 3

Hold the fitting body safely with a backup wrench and
tighten the nut 1-1/4 turn. (Marking the starting point at the 6 o'clock position will help reference the 1-1/4 revolution).
After 1-1/4 revolution, when the starting point is now at 9
o'clock position, you can easily confirm and see that
SUPERLOK Tube Fitting is installed accurately.
After 1-1/4 revolution of the SUPERLOK nut past
finger-tightening, make sure fitting is sufficiently
tightened using by the Gap Inspection Gage.
