KF flange series
Features
＊The typical KF or NW assembly consists of two identical flanges, a center-ring, and an aluminum clamp with a wingnut fastener frequently connect and disconnect without tools.
＊The mating flange surfaces compress an O’ring to generate a seal.
＊The vacuum seal is effected by uniform application of pressure by the clamp on 15º surface of the flange.

＊Hinged Clamp assemblies, detailed above, are the most commonly used method for making KF-Flange vacuum seal connections. Assembly is simplified by the 360° rotatable flanges and self-centering feature of the centering ring.
＊Pressure is applied uniformly around the 15° outer surface of both flanges by finger-tightening the single wingnut until the first metal-to-metal contact is made between the spacing lips of the centering ring and the inner surface of the mating flanges. This compresses the O’ring between the flanges and makes the vacuum seal.
Applications for KF vacuum components
＊Roughing and foreline plumbing for large vacuum system.
＊System demanding frequent cleaning.
＊System demanding frequent change.
＊Teaching laboratories.
＊Small system.
＊Experimental system in research laboratories.
