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. A variety of boltclamp options permit joints between mixed ISO-K and -F flanges. The design principles of ISO and KF seals are identical. Each flange face is counter-bored or grooved to receive a metal centering ring with an elastomeric o-ring around its O.D. As with KF, the ISO centering ring both aligns the flanges and holds the o-ring in place. ISO flanges are limited (by the o-ring's properties) to applications with temperatures between ~0° C and 120–180° C, and pressure from atmosphere to ~10-8 torr or mbar.

RANVAC ISO flange are manufactured according to ISO specifications with full compatibility to other manufacturers’ standard. There are two types of flange assemblies claw clamp type and bolt flange type; both use an O-ring hold in place by a centering ring to achieve vacuum seal up to 1x10-9mbar. The bolt type flanges are assembled by using a set of bolts to fix the position of the flanges. The claw clamp flanges use double claw clamps to hold two flanges together. The use of the claw clamps means that mating flanges can be connected in any orientation. Single clamp also can be used for certain applications.
