Abstract
A fixture for centering and holding an elastomeric O-ring in position between vacuum sealing flanges during assembly and use thereof, having an annular body defining an outer surface and O-ring holding flange disposed on the outer surface for holding an elastomeric O-ring. The outer surface of the annular body defines a pair of beveled surfaces which enable the fixture to be inserted between the vacuum sealing flanges during assembly thereof without any substantial binding. The annular body of the fixture also defines a cylindrical inner surface having a diameter which is substantially identical to the diameter of the cylindrical inner surfaces of the sealing flanges to substantially prevent turbulent gas flow effects.
