ISO Vacuum Flange Centering Ring Seals
ISO Stainless Steel or Aluminum centering rings include an Viton or Buna-N O-ring seal and Aluminum spacer ring. They are inserted between two ISO flange faces to provide the seal when joining ISO flanges. Viton O-rings are recommended when high temperature, chemical resistance or long installed life make them beneficial. Buna-N is used when temperatures are moderate, and installed useful life is consistent with this material.
