2.3.2 Reassembly Instructions
Swagelok tube fittings may be disassembled and reassembled many times.
Warning: Always depressurize the system before disassembling a Swagelok tube
fitting.
1)
Prior to disassembly, mark the tube at the back of the nut, then make a line along the
nut and fitting body flats.
These marks will be used during reassembly to ensure the
nut is returned to its current position.
Figure 5 - Marks for Reassembly
2)
Disassemble the fitting.
3)
Inspect the ferrules for damage and replace if necessary.
If the ferrules are replaced
the connector should be treated as a new assembly. Refer to the section above for
installation instructions.
4)
Reassemble the fitting by inserting the tube with preswaged ferrules into the fitting
until the front ferrule seats against the fitting body.

5)
While holding the fitting body steady, rotate the nut with a wrench to the previous
position as indicated by the marks on the tube and the connector. At this point, there
will be a significant increase in resistance.
6)
Tighten the nut slightly.
