Quick Overview
Rotatable blank Conflat flange (CF) consists of two parts, the inner knife edge detail and the outer bolt hole retaining ring which rotates around the inner part. This allows the boltholes to align to mating flanges in any orientation. These are used to blank off unused chamber ports for leak-tight assembly, also allowing End User machining for non standard tube sizes or components.
