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.

Swagelok recommends NO intermix/interchange of Swagelok tube fitting components with other manufacturers’ components.

  • No industrial design standard exists for two ferrule tube fittings. Each company makes components to its own design and not to any recognized standards.
  • Interchanging and intermixing tube fitting components can result in unpredictable performance, environmental releases, increased costs, and can be dangerous in critical applications.

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

Advanced-Geometry, Hinging-Colleting Back Ferrule Design

This design is standard on all 1/4 to 1/2 in. and 6 to 12 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.
