Vacuum Fittings - SS ScientificCF Components

SS Scientific offer a complete range of Conflat Flanges (CF) which are manufactured from high quality 304, 304L, 316 and 316LN stainless steel.

The CF series of flanges utilise the well proven captured copper gasket sealing principle which is universally used in the HV and UHV industry. The seal, an OFHC copper gasket, is held between the knife edges of a pair of CF Flanges.

This sealing method has a maximum bake out temperature of 450 degrees centigrade and is suitable for Ultra High Vacuum applications.

ISO Components

The ISO range of flanges and fittings are manufactured from high quality stainless steel.

The ISO flange uses an ‘O’ ring seal held in place by a centering ring, these flanges are effective for high vacuum applications and bake able to 200 degrees centigrade.

KF Components

The KF range of flanges and fittings are manufactured from high quality stainless steel.

KF flanges utilize an aluminum clamp with a single wing nut fastener allowing frequent disassembly without tools, the vacuum seal is affected by uniform application of pressure by the clamp on the 15 degree surface of the flange and the mating flange surfaces compress an ‘O’ ring held in place by a metal centering ring to produce a seal that can be used in high vacuum applications and baked to 200 degrees centigrade.

All the above flange types are fitted to a standard range of flexible bellows, straight connector, elbows, tee’s and other vacuum components.

SS Scientific also offer the option of customised fittings to meet your requirements with different flange connections on each sealing surface.
