Swagelok® Flange Adapters

Piping flange to Swagelok® tube fitting adapters provide a threadless, weldless transition from flanged piping systems to tubing systems, limiting potential leak points in applications such as instrumentation lines.

View Flange Adapters

Swagelok flange adapters provide a threadless, weldless transition from flanged piping systems to tubing systems. They are machined from one-piece integral forgings for optimal material strength at the fitting transition and to minimize opportunities for leaks.

Our flange adapters are available in a variety of alloys and designs to suit broad application requirements. Users can choose from a full range of sealing faces, including flat face, raised face, and RTJ versions. Flange adapters are available in flange types meeting ANSI, DIN, EN, and JIS standards in a full range of flange size, pressure classes, and sealing options. Flange adapters can include gaugeable Swagelok tube fitting end connections with wrench flats on the body for easy installation, as well as other end connections to meet system requirements.
