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.

The ISO flange (also called Large ISO) is used for HV chamber ports and is available in two distinct styles; ISO-K which uses clamp fasteners and ISO-F which uses nut and bolt fasteners. A variety of bolt/clamp options permit joints between mixed ISO-K and -F flanges. The design principles of ISO and KF seals are identical.

ISO-K DN 63 Blank Flange, Claw Clamp Type Flange, Stainless Steel. These ISO-K DN 63 blank flanges follow vacuum technology standards as described in DIN 28404 and ISO 1609. ISO-K fittings are quick to assemble using claw clamps (please see figure - click to enlarge) and can be connected together in any orientation.

CF63 - BoredTapped Flange, 63.5mm ID CF Bored Flanges Fixed are used for welding onto tube to produce ports and connectors when manufacturing fabrications. Manufactured from: 304L and 316L Stainless Steel. They are supplied in a plastic bag with a protective plastic cap.

These flanges are identical to the ISO NW flange standard. While these flanges are compatible with those made by European manufacturers, the tube diameter listed is in inches.
