The CF (ConFlat) flange is the most widely used for high vacuum and UHV applications. Many gauges, instruments, accessories and feedthroughs are available on this flange system.

Blank (Blind) Flange: A blank (blind) flange is essentially a solid plate or disc-shaped fitting used in vacuum systems. It can be machined to create a customized fitting or to close off an unused section of tubing or a port on a vacuum chamber.

The seal mechanism is a knife-edge that is machined below the flange’s flat surface. As the bolts of a flange-pair are tightened, the knife-edges make annular grooves on each side of a soft metal gasket. The extruded metal fills all the machining marks and surface defects in the flange, yielding a leak-tight seal. The CF seal operates from 760 torr (103 mbar) to < 1 x 10-13 Torr (< 1.3 x 10-13 mbar), and within the temperature range -196° C to 450° C (depending on material). Flange sizes in North America are normally referenced by their outside diameter (O.D.). However, in Europe and much of Asia, the nominal internal diameter (nominal I.D.) of the largest tube that can be welded to a bored flange is usually referenced in their nomenclature.

ConFlat flanges are offered in four versions:

  • Fixed flange: is a one piece design where the bolt-hole orientation is fixed with respect to that fitting.
  • Rotatable flange: is comprised of two parts, an inner weld ring and outer bolt ring. This enables the bolt ring to rotate about the inner weld ring.
