Vacuum Flanges and Hardware Components

Flanges are one of the most basic and essential parts to any vacuum chamber environment.   We offer a large selection of flanges in both the CF and ISO (KF,LF) style.

UHV CF Flanges

Our line of Ultra High Vacuum cf flanges are designed to incorporate the industry standard "captured copper gasket" sealing principle. This is the standard sealing method throughout the Ultra High Vacuum industry for CF vacuum flanges.  Vacuum Flanges listed here are blank flanges, meaning there is no through-hole.  Vacuum flanges have a vacuum rating to 1x10-10 Torr and temperature range of -200ºC to 450ºC.

If you require vacuum flanges with through-holes, please contact us.

ISO Flanges

Our line of ISO (KF,LF) flanges are designed to incorporate the industry standard Hinged Clamp (KF) or Claw Clamp (LF) with centering ring sealing principle.  This is the standard sealing method throughout the High Vacuum industry.  Again, flanges listed here are blank flanges, meaning there is no through-hole.   ISO vacuum flanges have a vacuum rating to 1x10-8 Torr and a temperature range of -26ºC to 150ºC (because of the type of Gasket that is used with these).

However, please contact us if you require flanges with through-holes as we can produce these flanges in less than 2 days lead time.

Mounting Hardware

In addition to the flanges below, the links will also take you the appropriate mounting hardware including copper gaskets, O-rings, claw clamps, hinge clamps, and bolt.
