ISO Flanges

The ISO range of flanges are manufactured from high-quality stainless steel.
ISO Vacuum Fittings
All configurations (shown Fig 2) use an ‘O’ ring seal (made of Nitrile or Viton) held in place by a centering ring & tightened together using wall clamps, double claw clamps or bolts.

There are different variants of ISO flanges available:

  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 into a rotatable ISO-F flange.

Please Note: Vacuum Services Ltd do not have a minimum order quantity, if your needs are for a 1 off flange, centering, gasket or clamp and we receive an order before 2,30pm we will ship to you the same day. If the product is in stock.
