Rotatable Bored CF Flanges

Rotatable bored Conflat Flat (CF) flanges are welded onto chamber tubulations or vacuum components. Smaller sizes of flange can accept a number of different standard tube sizes. The rotatable CF flange consists of two parts, the inner knife edge detail and the outer bolthole retaining ring which rotates around the inner part, this allows the boltholes to align to mating flanges in any orientation.
