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