Swagelok tube fittings come to you completely assembled, finger-tight and are ready for immediate use. Disassembly before use is unnecessary and can result in dirt or foreign material getting into fitting and causing leaks.
Swagelok tube fittings are installed in three (3) easy steps:
Step 1
Simply insert the tubing into the Swagelok tube fitting. Make sure that the tubing rests firmly on the shoulder of the fitting and that the nut is finger-tight.
Step 2
Before tightening the Swagelok nut, scribe the nut at the 6 o’clock position.
Step 3
Hold the fitting body steady with a backup wrench and tighten the nut 1 1/4 turns. À Watch the scribe mark, make one complete revolution and continue to the 9 o’clock position.
By scribing the nut at the 6 o’clock position as it appears to you, there will be no doubt as to the starting position. When the nut is tightened 1 1/4 turns to the 9 o’clock position, you can easily see that the fitting has been properly tightened. Use of the gap inspection gage (1 1/4 turns from finger-tight) ensures sufficient pull-up.
*For 1/16, 1/8, and 3/16 in.; and 2, 3, and 4 mm size tube fittings, only 3/4 turn from finger-tight is necessary.
