Swagelok® Tube Fittings and Adapters
Swagelok tube fittings deliver a leak-tight, gas-tight seal that is resistant to vibration fatigue, even in harsh environments or stressful applications. They withstand high pressures and temperature extremes and are easy to install, disassemble, and reassemble in a variety of situations. Swagelok tube fittings can be used on thick- or thin-walled, hard or soft tubing and resist the effects of pressure and thermal cycling.

The robust tube grip of the Swagelok tube fitting with its patented, two-ferrule technology is resistant to vibration fatigue and withstands high pressures and temperature extremes.
In the two-ferrule, mechanical grip design, the two ferrules separate sealing and tube gripping functions with each ferrule optimized for its function. The front ferrule creates a seal against the fitting body and on the tubing outside diameter. As the nut is turned, the back ferrule axially advances the front ferrule and radially applies an effective tube grip.
An advanced-geometry, hinging-colleting back ferrule design is standard on all 1/4 to 1 in. and 6 to 25 mm Swagelok stainless steel tube fittings to help installers make more consistent, leak-tight tube connections. In these sizes, a patented case hardening process and patented recessed and contoured geometry provide unique engineering to the Swagelok back ferrule. The hinging-colleting back ferrule design expands on the already robust performance of the traditional ferrule design.
