KF Flanges & Fittings
Ebara KF flanges are designed to ISO 2681 specifications for standard USA tube sizes from 3/8 to 2 inches OD. They are compatible with other manufacturers’ ISO-KF style flanges. KF flanges utilize an aluminum clamp with a single wingnut fastener or a lock-over-center clamp allowing frequent disassembly without tools.
Ebara manufactures a complete line of KF vacuum fittings. The tube portions are fabricated from 304 stainless steel. 316L stainless steel can be supplied on request. Ebara makes its own elbows, and all tees and crosses are made with the pulled-port technique. This allows smooth, crevice-free butt welds to provide the maximum in cleanliness for UHV applications.
