ISO Fittings

ISO Fittings


The ISO ranges of flanges and fittings are manufactured from high quality stainless steel.

There are various types of ISO flanges:

  1. ISO-K (clamp) flanges with a grooved ring for inserting wall clamps and double claw clamps are smaller and less expensive.
  2. ISO-F (fixed) flanges with a set of through-bore holes are pressed together with standard bolts. They are more stable than ISO-K flanges which enable them to mechanically support parts of the vacuum chamber.
  3. ISO bolt rings are used to make an ISO-K flange and ISO-F flange.
