The KF range of flanges and fittings are manufactured from high quality 316L (1.4404) stainless steel. KF flanges utilize an aluminium clamp with a single wingnut fastener allowing frequent dissassembly 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 on ‘O’-ring (held in place by a metal ring) to produce a seal that can used in vacuum applications down to 10 EXP -7 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 undergo a leak testing prior sales.
