Description
We offer all parts needed to connect and interact with a vacuum system. This includes clamping rings, vacuum tubes (flexible, straight, elbow cross, etc.), seals/o-rings, blanks, feed channels, etc.
Advantages:
• Availability of all components in short time
• Environmentally friendly and safe packaging
• Compatible with your existing flanges of the same system
• Highly airtight up to leakage levels of 1 x 10-9 mbar x l/s; all components are helium leak tested
• Low outgassing of materials through: - selection of the right material quality, especially for vacuum apparatus - excellent cleaning methods
• Documentation available for all components
Additional information
ISO-KF
The ISO-KF connection was developed by Leybold and is now the main flange type used for small fittings (up to 50 mm inner diameter) worldwide in every vacuum application.
It allows for quick assembly and replacement of components in vacuum systems by means of its quick release clamps, hence its alternative name, QF, Quick Flange.
Each connection consists of two symmetrical ISO-KF flanges, a galloping ring with O-ring seal and a clamping ring. High vacuum-tight ISO-KF connections can be made without the use of tools, simply by turning the wing nut of the clamping ring. It is typically suitable for pressures up to 10-7 mbar/torr, withstands pressures up to 5 bar and can be baked up to 200 °C when using metal seals or 150 °C when using FPM seals. The main feature, however, is the speed of assembly, with no tools required to ensure a vacuum tight seal.
ISO-K/ISO-F
For larger diameters you will usually find ISO-K and ISO-F fittings.
ISO-K fittings are often preferred as the clamps can be positioned at any point around the flange rather than at fixed bolted points. ISO-F flanges will be found where the flange is also used as a structural element due to their increased strength.
These types of flanges range from inside diameters to sizes from DN 63 to DN 630 (so pipe diameters from 70 to 650 mm). Since the centering ring can be firmly inserted into the centering groove of the flange, even horizontal connections are quickly and easily installed. With this type of connection, pressures of up to 10-9 mbar can be achieved when using metal gaskets. Again, a burn-in of up to 200 °C can be achieved when using metal flanges and 150 °C when using FPM.
CF
The CF flange connection consists of two geometrically identical flanges with a flat gasket made of OFHC copper, bolts, nuts and washers. The CF components are made of selected, corrosion-resistant types of stainless steel. This type of seal is very strong and CF flanges are therefore used when it is necessary to reach UHV pressures, which also require a burn-in (suitable with all metal gaskets). All components are welded from the inside to prevent from the outset any cracks or holes that could represent a so-called virtual leak. Available in sizes from DN 16 CF to DN 250 CF (ID 16 mm to 250 mm), they are often found in pressure gauges, ion pumps and turbomolecular pumps used to achieve ultra-high vacuum pressures.
Feedthroughs
The need for control within and transfer of power to the vacuum is managed through feedthroughs. We have a range of standard and high current feedthroughs. Then we have a range of rotary, fluid, rotary/linear to transfer force/objects into the vacuum system.
