CF Vacuum Fittings Overview
There is no general standard for CF flanges
NW250 and over, however, two “standards” have come into use, one European and one Anglo-American, both
of are available in our product line. Other standards are in use at research centre’s.and used by some other manufacturers.
Sealing of the CF flanges is provided by use of Oxygen-free copper (OFHC) flat gasket rings for UHV bakeability requirements, which usually can only be used once due to deformation. The tightening pressure is exerted by screws that have to be tightened uniformly and crosswise to avoid excessive strain.
