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 Swagelok nuts and ferrules
2
Clamp a stainless steel plug or similar fitting in a bench vise.
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.

Important!
The narrow end of the
back ferrule fits into
the rear of the front
ferrule.
