KF Vacuum Fittings Overview



The KF range of fittings and flanges are manufactured from stainless steel. KF flanges are held together with an aluminium clamp by means of a single wingnut fastener. This allows frequent disassembly without tools.

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

Advanced sealing material such as copper or aluminium can be used, if the joints need to operate or be baked at higher temperatures or if corrosion resistance is required.

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

All components are Helium leak tested.
