一、概述


The CF (ConFlat) flange is the most widely used for high vacuum and UHV applications. 


The seal mechanism is a knife-edge that is machined below the flange's flat surface. 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 Pressure range:  1 bar to 10-12 mbar)

Operating temperature :-196° C to 300° C
