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
1 Place a Swagelok nut, back ferrule, and front ferrule to the
tubing as shown in
Front ferrule

Figure 48 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.
