ABSTRACT:
A reusable plug device for providing sealing of an opening of a rim of a wheel for leak testing has a simple structure and facilitates installation/removal of the plug device using a simple insertion tool and a removal tool. The plug body has an axially extending cavity for receiving the insertion tool to enable the plug body to be inserted until a flange section of the plug body abuts the surface of the workpiece. The flange section serves as a stopper to indicate the stop position and ensures a uniform installation of the plug device in each workpiece. For removal of the plug body, the removal tool is inserted into the cavity and the removal tool is pushed in the insertion direction, so that the plug body and the flange section both collapse inward into the cavity to enable the plug device to be simply pushed out through the opening section.
