The following procedure reviews how to make Swagelok connections. This
procedure explains how to connect tubing to a fitting, such as the sample inlet(s),
carrier gas inlet(s), or the gas supply tank.
Materials Needed
 1/8 in. OD pre-cleaned copper or stainless steel tubing
 1/8 in. Swagelok nuts, and front and back ferrules
 Two 7/16 in. wrenches for 1/8 in. tubing
 Two 5/16 in. wrenches for 1/16 in. tubing
Procedure
1 Attach a 1/8 in. Swagelok nut, back ferrule and front ferrule to the tubing as
shown in
