CF zero length reducer

HIS manufactures a complete line of knife-edge CF style flanges using our CNC lathes. This ensures consistency, tight dimensional tolerances, and fine surface finishes. These flanges conform to industry standards and are interchangeable with all other CF fittings. Fittings are made of 304 stainless steel, but 316 is available upon request.

Guaranteed leak-free from 1X10^(-13) torr and in temperature ranges from -196° C to 500° C.

Measurements are listed in inches (mm).
