C.2.1 Installation Procedure
Swagelok Tube Fittings come completely assembled, finger-tight, and are ready for
immediate use. Disassembly before use is unnecessary and could result in dirt or foreign
material getting into the fitting and causing leaks.
Perform the following procedure to install Swagelok Tube Fittings:
1. 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 finger-tight.
