CF Blank Flanges

The CF (ConFlat) flange are most widely used in high vacuum and Ultra high vacuum (UHV) applications. The seal mechanism in this flanges is a knife-edge that is machined below the flange's flat surface and soft metal gasket is used to seal two flanges, as the bolts of a flange-pair are tightened, the knife-edges make annular grooves on each side of a soft metal gasket. The extruded metal fills all the machining marks and surface defects in the flange, yielding a leak-tight seal.

The CF seal operates from 103 mbar to < 1.3 x 10-13 mbar, and within the temperature range -196° C to 450° C and it depends on the soft metal gasket used to seal the component. CF blank flange dimension is maintained as per international standards. These blank flanges are machined using stainless steel 304 or 316L material.
