Assembly Instructions
SABE Fittings are supplied assembled and finger-tightened. They are ready for immediate use. Disassembly before use can result in dirt or foreign material getting into the fitting, which can cause leaks.
1. Insert the tubing into the Tube Fitting. Make sure that the tubing rests firmly on the shoulders of the fitting and that the nut is snug-tight. In this position, the tube does not rotate by hand.
2. Before tightening the nut, it is recommended that a scribe mark be drawn on the hex of the nut extending onto the fitting body, as position “0″. This mark will serve as an indicator for the starting point and proper pull-up.
3. While holding the fitting body steady with a backup wrench, tighten the nut 1-1/4 turns, Watch the scribe mark and make one complete revolution. Then continue turning to the position End as per figure A. (For 1/8″ and 3/16″ size tube fittings, only 3/4 turns from finger-tight is required as Figure B)
