our CF vacuum range comply with ISO 3669 standard and up to NW200 are compatible with ConFlat flanges and CF flanges of other leading manufacturers.


While there is no general standard for CF flanges NW250 and over, essentially two “standards” have come into use, one Anglo-American and one European, both of which are available in our product line. Other standards are used by some other manufacturers and in use at research centre’s.


Due to UHV bakeability requirements, sealing of the CF flanges is provided by use of Oxygen-free copper (OFHC) flat gasket rings which usually can only be used once due to deformation. The tightening pressure is exerted by through-bore screws that have to be tightened uniformly and crosswise to avoid excessive strain.
