Feedthrough for gas or fluid, mainly for delivering liquid or gas to a device inside a vacuum chamber, often to maintain the device's temperature or to actuate a pneumatic mechanism.

Occasionally, liquid-gas FT connects to internal devices that are not electrically grounded. For these applications, use electrically isolated power FT with tube conductors.

Cryogenic feedthroughs are similar to gas-liquid FT except for a longer thermal path between tube and flange. Heat transfer is reduced and thus minimizes cryogenic evaporation rate.

End connection is available in Swagelok, VCR, or welded type.

Drawings and specifications available upon request.
