Iso Standard Square Tube Sizes
A KF-25 tee, o-ring, and clamp The standard quick release flange is known by the names Quick Flange (QF), Klein Flange (KF) or NW, sometimes also as DN. The KF designation has been adopted by ISO, and. KF flanges are made with a back surface that are attached with a circular clamp and an that is mounted in a metal centering ring.
Standard sizes are indicated by the nominal inner diameter in millimeters for flanges 10 through 50 mm in diameter. Sizes 10, 20 and 32 are less common sizes (see ). Some sizes share their flange dimensions with their respective larger neighbor and use the same clamp size. This means a DN10KF can mate to a DN16KF by using an adaptive centering ring.

DN40KF. DN50KF ISO The ISO large flange standard is known as LF, LFB, MF or sometimes just ISO flange. As in KF-flanges, the flanges are joined by a centering ring and an elastomeric o-ring. An extra spring-loaded circular clamp is often used around the large-diameter o-rings to prevent them from rolling off from the centering ring during mounting.
The ISO large flanges come in two varieties. The ISO-K (or ISO LF) flanges are joined with double-claw clamps, which clamp to a circular groove on the tubing side of the flange. The ISO-F (or ISO LFB) flanges have holes for attaching the two flanges with bolts. Two tubes with ISO-K and ISO-F flanges can be joined together by clamping the ISO-K side with single-claw clamps, which are then bolted to the holes on the ISO-F side. ISO large flanges are available in sizes from 63 to 500 mm nominal tube diameter:. DN63LF (63.5 mm).
DN100LF (102 mm). DN160LF (160 mm). DN200LF (200 mm). DN250LF (254 mm). DN320LF (316 mm). DN400LF (400 mm).
DN500LF (500 mm) CF (Conflat). A 60 kV electrical feedthrough on a 4½ inch (or DN63) conflat flange Several vacuum flange exist, and the same flange types are called by different names by different manufacturers and. CF (ConFlat) flanges use a copper gasket and knife-edge flange to achieve an seal.

The term 'ConFlat' is a registered trademark of, so 'CF' is commonly used by other flange manufacturers. Each face of the two mating CF flanges has a knife edge, which cuts into the softer metal gasket, providing an extremely leak-tight, metal-to-metal seal. Deformation of the metal gasket fills small defects in the flange, allowing Conflat flanges operate down to 10 −13 (10 −11 ) pressure. The knife edge is recessed in a groove in each flange. In addition to protecting the knife edge, the groove helps hold the gasket in place, which aligns the two flanges and also reduces gasket expansion during. For stainless-steel conflat flanges, baking temperatures of 450 °C can be achieved; the temperature is limited by the choice of gasket material. CF flanges are sexless and interchangeable.
In North America, flange sizes are given by flange outer diameter in inches, while in Europe and Asia, sizes are given by tube inner diameter in millimeters. Despite the different naming conventions, the actual flanges are the same. European, Asian size North American size inches DN10 1 DN16 1⅓ ('mini') DN25 2⅛ DN40 (or DN35) 2¾ DN50 3⅜ DN63 4½ DN75 4⅝ DN100 6 DN125 6¾ DN160 (or DN150) 8 DN200 10 DN250 12 13¼ 14 16½ ConFlat gaskets were originally invented by William Wheeler and other engineers at Varian in an attempt to build a flange that would not leak after baking.
Wheeler A Wheeler flange is a large wire-seal flange often used on large vacuum chambers. ASA has a flange standard called ASA. These flanges are elastomeric o-ring seal and can be used for both vacuum and pressure applications. Flange sizes are indicated by tube nominal inner diameter or by flange outer diameter (in inches): 1 (4.25 O.D.), 1.5 (5.00 O.D.), 2 (6.00 O.D.), 3 (7.50 O.D.), 4 (9.00 O.D.), 6 (11.00 O.D.), 8 (13.5 O.D.), 10 (16.00 O.D.).

Vacuum gaskets To achieve a vacuum seal, a is required. An elastomeric gasket can be made of, fluoropolymer,. O-rings can be placed in a groove or may be used in combination with a centering ring or as a 'captured' o-ring that is held in place by separate metal rings. Metal gaskets are used in ultra-high vacuum systems where the of the elastomer could be a significant gas load. A copper ring gasket is used with conflat flanges. Metal wire gaskets made of copper, or can be used.
Vacuum feedthrough A vacuum feedthrough is a flange that contains a vacuum-tight electrical, physical or mechanical connection to the vacuum chamber. An electrical feedthrough allows voltages to be applied to components under vacuum, for example a. An example of a physical feedthrough is a vacuum-tight connection for cooling water.
A mechanical feedthrough is used for and of components under vacuum. A wobble stick is a mechanical feedthrough device that can be used to pick up, move and otherwise manipulate objects in the vacuum chamber. See also.
