Swagelok® Gaugeable Tube Fittings and Adapter Fittings

Tube Fittings

The live-loaded, two-ferrule tube fitting is easy to install, with no torque transmitted to tubing during installation. The Swagelok gap inspection gauge ensures sufficient pull-up upon initial installation.

Swagelok tube fitting performance in extreme conditions has been proven with over 65 years of success and documented in numerous published test reports. See the performance demonstrated live during eight tests in the video, "Swagelok Tube Fitting Extreme Testing".

  • Boreline seal and metal-to-metal stop virtually eliminate fluid holdup and improve drainability and cleanability.
  • Seals remain leak-tight throughout pressure-temperature ratings range.
  • Clamp and ferrule assemble easily as ferrule captures self-aligning gasket.
  • TS series adapter gasket allows an existing ISO 2852 ferrule to mate with a TS series ferrule.


Ferrules are cleaned to ensure components are free of burrs, chips, loose particles, oil, grease, and other contaminants. Electropolished ferrules are passivated.
