Swagelok tube fittings deliver a leak-tight, gas-tight seal in an easy-to- install, disassemble and reassemble form. The robust tube grip with patented, two-ferrule technology is resistant to vibration fatigue and withstands high pressures and temperature extremes.

Two-Ferrule, Mechanical Grip Design

The two ferrules separate sealing and tube gripping functions; each ferrule is 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
