ISO Replacement Retaining Rings

These bolt rings and replacement retaining rings are used for mating ISO-K to ISO-F style flanges of the same size. The ISO flange (also called Large ISO) is used for HV chamber ports and is available in two distinct styles; ISO-K which uses clamp fasteners and ISO-F which uses nut and bolt fasteners.

ISO Bolt Rings & Retaining Rings:

  • Used to mate ISO-F to ISO-K style flanges
  • Bolt rings constructed of aluminum and include the retaining ring
  • Replacement retaining rings DO NOT include the bolt ring
