CF Fittings

CF fittings seal with a knife-edge machined into the mating flange. Typical seal is an OFHC - (oxygen free high conductivity) copper gasket, although elastomer seals can also be used. The name CF is short for ConFlat. CF flanges are used in vacuum and ultra high vacuum (UHV) applications.

CF 6-Way Cube Crosses

6-way CF cube crosses machined from a block of 304 stainless steel. The crosses use copper gaskets and knife-edge flanges to achieve the high vacuum seal.

Mounting holes are threaded into the body of the cross. The threaded holes from two adjacent faces do not intersect each other because the bolt patterns are slightly rotated around the axis of each cube face.
