Abstract
A rotatable vacuum flange includes a flange ring having a recess, an insert mounted in the recess in the flange ring, the insert including a seal portion and being adapted for vacuum-tight attachment to a vacuum conduit, and a wire spring positioned between the flange ring and the insert. The wire spring retains the insert in the recess in the flange ring and permits rotation of the insert relative to the flange ring. The flange ring and the insert include grooves located in opposing alignment to receive the wire spring.
