Specifications
ISO Flanges
ISO flanges are designed to fit tubes with OD above 2 inches. Hositrad ISO flanges are manufactured according to ISO specifications
with full compatibility to other manufacturers' standards. There are two types of flange assemblies, claw clamp (ISO-K) and bolt flange (ISO-F).
Both use an O-ring hold in place by a centering ring to achieve vacuum seal up to 1x10-9 mbar.
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 together in any orientation.
