The KF range of flanges and fittings are compatible with those of all other leading manufacturers and are made from high quality 316L (1.4404) stainless steel. KF flanges utilize an aluminium clamp with a single wingnut fastner allowing frequent disassembly without tools. The vacuum seal is effected by uniform application 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 centering ring) to produce a seal that can be used in vacuum applications down to 10-7 mbar and baked to 200°C (sustained to 150°C).
