ISO KF Flanges and fittingsIntroductionUHV SeriesISO KF Typical installation
ISO KF Flanges and fittingsIntroductionISO KF vacuum systems employ components with metric interface dimensions which have been defined by the International Standards Organisation (ISO).This ensures a high degree of compatibility between components obtained from different sources. MDC Vacuum ISO KF are compatible with Klein Flange (KF) types. Use ISO KF for tube sizes DN16 to DN50.Clamp
K40 (2 places)
Our standard range of KF flanges and fittings are manufactured from 304 (1.4301) stainless steel. ISO KF constitutes an economical system of reusable interfacing stainless steel vacuum fittings and components for 19.1, 25.4, 38.1 and 50.8mm OD tubing. Assemblies are usable to 10-8 mbar. Maximum temperature for sustained use is 150C. T hey are ideal for vacuum systems requiring regular assembly and disassembly. Each vacuum seal is made by compression of an O-ring on a centring ring between mating flanges. The seal is made in seconds by finger-closure of a wing nut on the all-metal hinged aluminium clamp.ISO DN16KF DN25KF DN40KF DN50KF DN63LF DN100LF DN160LF DN200LF DN250LF DN320LF DN400LF DN500LF Nominal tube ID mm 16 25 40 50 63.5 102 153 212 254 316 400 500

The ISO KF family of modular building block components includes all commonly used standard fittings, feedthroughs and accessories. Reducing flanges are available to connect different size components. Mating flanges are offered to interface with pipe and other flange systems including LF and CF.

Centring ring assemblies are placed between two ISO flanges with matching outer diameters. The widest portion of the centring ring rests inside a capture groove on the flange and the O-ring rests on the flat polished surface outside the capture groove. On a blank flange, the groove seen on the face of a flange is the capture groove, with the O-ring making contact with this flange face just outside the groove.
Hinged clamp assemblies are the most commonly used method for making ISO KF vacuum seal connections. Prior to clamping, flanges can be rotated 360 and accept self-centring centring ring seals. Pressure is applied uniformly around the 15 outer surface of both flanges by finger-tightening
the single wing nut until the first metal-to-metal contact is made between the spacing lips of the centring ring and the inner surface of the mating flanges.This compresses the O-ring between the flanges and makes the vacuum seal.

Bolted bulkhead clamps are commonly used to fasten ISO KF components to flat chamber walls or baseplates. Use of this product requires customer machining of six or eight M5 threaded bolt holes on the mounting surface.

ISO LF Flanges and fittingsIntroductionMDC Vacuum Limiteds ISO LF components are an economical system of reusable and interfacing stainless steel vacuum fittings for tube sizes ranging from 63.5mm through to 500mm diameters. ISO LF flanges pick up where the ISO KF system leaves off. These flanges can operate in high vacuum environments to pressures in the 1x10-8 mbar range. The ISO LF flange system is ideally suited for applications requiring rapid and frequent assembly and disassembly. MDC Vacuum ISO LF flanges comply with all ISO specifications for vacuum mounting hardware and are compatible with most third party ISO LF flanges and components. The primary method of fastening and sealing is achieved by using multiple double claw-clamp assemblies to provide uniform compression of an elastomer gasket trapped between two mating flanges. The elastomer gasket is mounted on an aluminium centring ring that has tubular rims or extensions that protrude on either side of the gasket. These rims or extensions fit into grooves on the corresponding mating flanges and conveniently centre the gasket between the flanges prior to sealing. A reliable seal is then made by tightening bolts in an alternating, crisscross pattern and thus applying uniform pressure around the entire flange sealing surface. Single claw-clamps are ideally suited for applications where one of the mating flanges is flush mounted and fitted with threaded bolt holes. Both the double and single claw-clamp fasteners provide unlimited rotation or positioning of mating flanges prior to final tighteningBolt flangesNumber 3 to 4 4 to 8 4 to 8 6 to 12 6 to 12 8 to 12 8 to 16 12 to 16 OD 130 165 225 285 335 425 510 610 Thickness 12 12 16 16 16 20 20 20 Bolt circle diameter 110 145 200 260 310 395 480 580 Holes 8.9 8.9 10.9 10.9 10.9 14.0 14.0 14.0 Bolt holes 4 x M8 8 x M8 8 x M10 12 x M10 12 x M10 12 x M12 16 x M12 16 x M12 Spacer ring Bolted flange
ISO LF Flanges and fittingsIntroductionof bolts. Bolted rotatable adaptor rings provide a convenient way of fastening claw style flanges to threaded ISO LF flanges, without the use of individual clawclamps. Rotatable bolt rings are ideally suited for use in applications where low profile geometry is required. Bolted non-rotatable ISO LF flanges use bolts for fastening and are typically used where single claw fasteners are not desirable. They too, are ideally suited for use in applications where low profile geometry is required, but do not offer rotatable construction. The MDC Vacuum ISO LF family of modular building-block components includes all of the commonly used standard hardware and fittings. Reducer flanges are available to connect different size ISO components. Hybrid adaptors are available to connect ISO LF components to non ISO vacuum fittings and mounts. In general, MDC Vacuum components compare with international components using an inch-to-millimetre ratio. US sizes refer to a tubes outside diameter, whereas international sizes refer to a tubes inside diameter.LF flange

Double claw-clamp assemblies are commonly used for making vacuum seal connections. Assembly is simplified by the 360 rotatable flanges and the self-centring feature of the centring ring. Single claw-clamp assemblies are used to mate a clamp-style to a threaded boltstyle such as on a gate valve. The vacuum seal is
made by compressing the O-ring between the mating flanges. This is done by alternately spanner-tightening opposing pairs of clamps until the first metal-to-metal contact is made between the inner surfaces of the flanges and the spacing lip of the centring ring.

Slip the bolt ring over a standard claw-clamp style flange and install the retaining ring. After the bolt ring has been rotated to align the bolt holes, the vacuum seal is made by alternately
spanner-tightening opposing pairs of bolts. One complete rotatable bolt ring assembly consists of one aluminium bolt ring and one retaining ring.

ISO KF and LF fittingsIntroductionUHV SeriesNuts and washers included
DescriptionMDC Vacuum ISO KF and ISO LF tube fittings are convenient building-block components. They offer great flexibility in the design and construction of high vacuum systems. All fittings are fabricated from 304 stainless steel drawn and welded vacuum tubing. Flanges do not need to be rotatable since they are completely symmetric. If desired, rotatable bolt ring assemblies can be retrofitted to existing claw-clamp style flanges to add bolt holes to ISO LF fittings. 31 31 26 26 26 62 62 62

Reducers are used for a change in size of flanges within a single method of sealing, such as elastomer sealing of ISO KF and LF flanges. Note Zero-length reducers are not possible with ISO style flanges.
