KF Vacuum Fittings

The KF ranges of flanges and fittings are manufactured from high quality stainless steel. KF flanges utilize an aluminium 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. 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.

ISO Vacuum Fittings

The ISO ranges 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 bakeable to 200 degrees centigrade.
