The Swagelok Tube Fitting is designed to provide a leak-tight seal for pressures up to the suggested allowable pressure rating of the tubing. The two-ferrule, mechanical-grip, hinging-colleting type connection consists of a fitting body, a nut, a front ferrule, and a back ferrule.
How does Swagelok seal?
Gas seal. A Swagelok tube fitting forms a gas seal by means of the burnishing that occurs in two places: between the front ferrule and the tube fitting body, and between the front ferrule and the tubing.
How tight should Swagelok fittings be?
While holding fitting body steady, tighten the plug one-quarter turn from the finger-tight position. For 1/16, 1/8, and 3/16 in.; 2, 3, and 4 mm tube fittings, tighten the plug one-eighth turn. For over 1 in. and over 25 mm tube fittings, tighten the plug one-quarter turn.

Over tightening a compression fitting can also cause the fitting to leak. When tightening up the compression fitting, only turn your tool until you feel resistance. From there, you shouldn’t turn it anymore than a half a turn. By doing this, you can ensure you’ll prevent your compression fitting from leaking.
