Swagelok - Better by Design

Fitting Design

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


How does the Swagelok tube fitting OUTPERFORM? Not only does our hinging and colleting design provide optimal performance for tube grip, gas seal, and vibration resistance, but the unique SAT 12 low-temperature carburization process produces tool steel-like hardness and strength in the ferrule without sacrificing corrosion resistance or material ductility.


  • Uses standard tools and utilizes reasonably less torque than other competitive brands
  • Swagelok tube fittings come fully assembled and connections can be reassembled many times


  • Swagelok performs continuous, rigorous testing on thousands of samples of production tube fittings to ensure only highly reliable components
  • We publish the most comprehensive book of tube fitting Product Test Reports (PTRs) in the industry - Click here to download
