Flange coupling for the vacuum industry
ISO
A&N Corporation
ISO-QF (Quick Flange) and LF (Large Flange) flanges are part of the same family of ISO standard elastomer sealed vacuum components designed for high vacuum service. A&N 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 vacuum systems. ISO flanges, along with CF flanges, represent the most commonly used vacuum flange systems around the globe.
Standard QF flanges have bore (tube) sizes that range from 16mm to 50mm (QF16 to QF50). In addition, A&N offers a range of QF flanges from 63 to 200mm. QF flanges are fastened with quick style clamps and are sealed with an elastomeric o-ring. LF flanges have bore (tube) sizes that range from 63mm to 500mm (LF63 to LF500). LF style flanges are fastened with claw-style clamps or with bolts. Adaptive bolt rings are available that allow the conversion from claw-style flanges to bolt-style flanges. LF flanges are also sealed with an elastomeric o-ring.
