Aluminum half-moon clamps are applied to fix KF flanges in vacuum systems.
This product fits base plates or smooth walls equipped with six or eight #10-32UNF (or M5×16L) threaded mounting holes.
The clamps align with standard KF sealing assemblies consisting of a KF flange and an O-ring fitted centering ring, and are fastened to the matching bolt holes to form a vacuum seal between connected parts.
Standard sizes of the half-moon clamps cover KF10, KF16, KF25, KF40 and KF50.
