Rotatable Blank CF Flanges

The rotatable Conflat flange (CF) 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. The rotatable nature of the CF flange allows any bolt hole orientation to be easily accommodated. Universal fit for VACGEN Gaskets and bolt kits.
