Making Swagelok Connections
Objective
To make a tubing connection that does not leak and that can be
taken apart without damaging the fitting.
Materials needed:
• 1/8-inch (or 1/4-inch, if used) preconditioned copper tubing
• 1/8-inch (or 1/4-inch, if used) Swagelok nuts
• Front and back ferrules
• Two 7/16-inch (for 1/8-inch nuts) or 9/16-inch (for 1/4-inch
nuts) wrenches
•
Procedure:
1
Place a Swagelok nut, back ferrule, and front ferrule to the
tubing as shown in
Figure 17 .
Figure 17 Swagelok nuts and ferrules
2
Clamp a stainless steel plug or similar fitting in a bench vise.

Tubing
Important!
The narrow end of the
back ferrule fits into
the rear of the front
ferrule.
CAUTION
Do not
Use a separate stainless steel fitting in a vise for initial tightening
of the nut. Do not use an inlet or detector fitting. Strong forces are
required to properly set the ferrules, and damage to an inlet or
detector fitting is very costly to repair.
