KF Fittings


The KF ranges of flanges and fittings are manufactured from high quality stainless steel. KF flanges utilize an aluminium clamp with a single wingnut fastener allowing frequent disassembly without tools.

The vacuum seal is effected by uniform applications of pressure by the clamp on the 15° surface of the flange. The mating flange surfaces compress an ‘O’-ring (held in place by a metal ring) to produce a seal that can used in vacuum applications down to 10-8 mbar and baked to 200°C (sustained to 150°C)

Advanced sealing material such as aluminium or copper may be used, when the joints have to be operated or baked at elevated temperatures or if high corrosion resistance and/or electrical insulation are required.

Our vacuum components are bead-blasted inside and outside, unless otherwise stated. The sealing faces are polished mechanically.

All components are subjected to a leak testing protocol.
