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.
This unique low temperature carburization process produces tool steel like hardness and strength in the ferrule without sacrificing corrosion resistance or material ductility.
