ConFlat (CF) UHV Flanges
The ConFlat (CF) flange system provides a complete range of ultra-high vacuum (UHV) flanges to mount with tubing sized ¾-inch up to 14-inch diameter. CF flanges have a pressure range of approximately 1×10-13 Torr.
CF Flanges are available in two general styles: fixed and rotatable. Fixed flanges have a set bolt hole orientation, while rotatable flanges have a two-piece design allowing for bolt hole rotation to ease bolt alignment when mating the two flanges.
Both fixed and rotatable flanges are available with clearance and tapped bolt holes. Clearance bolt holes allow for unrestricted passage of a bolt through the flanges. The bolt is then tightened with a nut on the back side of the flange assembly. Tapped bolt holes are threaded to receive and tighten the bolt directly and do not utilize a nut.
All flanges offered by ANCORP are manufactured on state-of-the-art CNC (computer numerical control) lathes to ensure consistency with dimensional tolerances, and extremely fine surface finishes.
CF flanges have a standard material offering of 304L and 316LN stainless steel. Other materials such as 316L stainless steel and 6061 T6 aluminum are available upon request.
