ISO FLANGES

ISO flanges are designed to fit tubes with OD above 2 inches. Hositrad 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 1x10-9 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. STANDARD SPECIFICATION
