The device i.e. sealing plug (20), has a metal insert (22) with a cylindrical or conical disk face (28) whose outer surface is covered with an elastic coating (24) compressed between the insert and an engine. The face of the insert presents a shape adapted to expand radially and to reinforce compressive effort of the coating. The insert includes tabs extending radially along length such that ends of the tabs are in contact with a wall of an orifice of the engine, and generate concentric efforts which permit to deform the insert and to allow expansion of the face when the device is installed. The coating is realized in Acrylic Rubber type material or Fluorocarbon Rubber type material. |
