A plug for sealing an aperture in a panel includes a body portion adapted to close the aperture, a flange portion adapted to overlie an upper surface region adjacent the aperture, one or more insert portions adapted for insertion through the panel in contact or close adjacency to the edge surface of the aperture, and a body of sealant material in the form of a ring in contact with the under surface of the flange portion. The sealant material has the property of flowing when heated to an operating temperature lower than the melting point of the plug material, and the insert portion or portions of the plug and the body of sealant are formed so as to cause at least part of the sealant, upon being heated, to flow and adhere between the edge surface of the panel aperture and at least part of an insert portion.
