ISO (QF/LF, KF, NW/ISO-K) Flanges and Fittings

 

ISO-QF (Quick Flange) and LF (Large Flange) flanges are part of the same family of ISO standard elastomer sealed vacuum components. ANCORP ISO flanges and fittings are manufactured in accordance with ISO (International Standard Organization) 2861 standards and tolerances. These flanges are an economical, convenient and simplified means of constructing custom high vacuum systems.

 

ISO flanges provide a complete range of fittings to mount with tubing sized 1/2 inch up to 20 inches in diameter. The flange system consists of two sexless, 360° rotatable flanges, a centering ring for alignment and support of the sealing ring and a fastener to compress the seal between the two flanges. ISO-QF and LF sealing components are similar, however, their fastening methods differ. ANCORP offers a complete line of flanges, fittings, valves, traps and accessories with ISO connections that can be used to create a complete vacuum system or pumping line.
