Swagelok Tube Fitting Advantage

Better By Design

Swagelok developed the original two-ferrule tube fitting in 1947, and with 200 active patents worldwide, we continue to improve our proprietary design for use in thousands of diverse applications.


We out perform in three key areas;

Tube Grip | Gas Seal | Vibration Resistance

Swagelok tube fittings have a grip-type design that uses a unique “hinging and colleting” action to achieve optimal performance in three key areas:

  • Tube grip—hinging colleting action provides more direct tube contact/gripping support
  • Gas seal—burnishing/polishing action of the front ferrule creates concentrated zones of contact on the tube and on the body bevel for a stronger seal
  • Vibration resistance—the colleting region better isolates stress risers at the tube grip to resist bending, deflection, and vibration


"This is one of the most significant breakthroughs in material science in many decades, as well as one with many extraordinary technical implications.” - ARTHUR HEUER, PHD, KYOCERA PROFESSOR OF MATERIALS, CASE WESTERN RESERVE UNIVERSITY

SAT12 is Swagelok’s unique low-temperature carburization process.

  • Diffusing carbon atoms between metal atoms without forming carbides
  • In use for nearly two decades
