KF FLANGES

Hositrad flanges are designed in accordance with International Standards Organization specifications which are compatible with other manufacturers’ KF-ISO flange design.
Standard materials are in stainless steel 304 and 316L. Aluminum is also available upon request. KF flanges allow easy and quick disassembly for repeatable uses. Flange connections are available for tube size from KF10 – KF50. KF flanges utilize an aluminum clamp with a single wing nut clamp allowing frequent disassembly without tools. The degree taper surface of flanges allows uniform pressure for compressing an O-ring held in place by a centering ring.
The vacuum seal can be applied up to 1 x 10-9 mbar, depeding on gasket material,and baked to 200°C.
However, sustained baking above 200°C may result in deterioration of O-rings.
Hositrad provides a broad range of KF adaptors for connecting to different types of flanges. STANDARD SPECIFICATION
