Abstract

See full text

A thin flange, for use with a vacuum system, includes a member having a diameter and a thickness. The member has a first face having a first sealing surface. The member has a second face opposed and substantially parallel to the first face. The second face has a second sealing surface. The thickness of the member is less than previously attained. In some designs, the thickness of the member is less than 0.28 inches.
