ISO COMPONENTS The ISO range of flanges and fittings are manufactured from high quality stainless steel. All shown configurations use an 'O' ring seal (made of Nitrile or Viton) held in place by a centerring ring. Tightening pressure is exerted with clamps, claw clamps or bolts. This effective down to 10 EXP-8 mbar. With Viton 'O' rings the assemblies are bakeable to 200°C (sustained 150°C). There are various types of ISO flanges: 1, ISO-K (clamp) flanges with a grooved ring for inserting clamps and 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. The various combination of the ISO flanges are shown as follows.NW of the flange no. of required clamps NW 63 4NW 80 4NW 100 4NW 160 4NW 200 6NW 250 6NW 320 8NW 400 8NW 500 12NW 630 12AISO-K flange fixed to vacuum chamber using wall clamps B ISO-K flange fixed to ISO-F flange using wall clamps, nuts and washers Ctwo ISO-K flanges fixed together using double claw clamps, which is the most commonly used configuration D ISO-F flange fixed to vacuum chamber using bolts, washers and tapped blind holes E ISO-K flange fixed to ISO-F flange using bolt rings, bolts, nuts and washers F two ISO-F flanges fixed together using bolts, nuts and washers 10VacuumServicesABCDEF
