Appendix F: Swagelok tube fittings
Appendix F.1: Installation instructions
Swagelok tube fittings come to you completely as-
sembled, 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 easy
steps
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 fin-
ger-tight.
2. Before tightening the Swagelok nut, scribe the
nut at the 6 o’clock position.
3. Hold the fitting body steady with a backup
wrench and tighten the nut 1 1/4 turns. Watch
the scribe mark, make one complete revolution
and continue to the 9 o’clock position. By scrib-
ing 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.
