ISO KF flanges according to ISO 2861 (DIN 28403)

Our flanges are manufactured from high-quality stainless steel (1.4435). The conical face is hardened to prevent a clamping of the chain clamps.

We stock the nominal diameters 10/16, 20/25, 32/40, 50 and 63.

The ISO Konus system offers space and time saving assembly in comparsion to the ISO K system.

The flanges can be connected fast and reliable with the chain clamp.

We stock the nominal diameters 63, 80, 100, 125, 160, 200 and 250. 

Other nominal diameters upon request. 

ISO-K System according to ISO 1609 oder DIN 28404

The ISO K system is connected with clamp screws or brackets. Alternatively a collar flange can be used.

We stock the nominal diameters 63, 80, 100, 125, 160, 200 and 250.

CF or also called Conflat flanges, are used with Ultra High Vacuum (UHV) applications. The seal consists of copper, therefore these connections can be very highly baked. For test purposes there are also elastomer seals available.

We stock the nominal diameters 16, 40, 63, 100, 160, 200 and 250.
