ABSTRACT:
A sealing ring made up of nestable elements is constructed by forming a basic cylindrical-frustoconical element having the function of withdstanding the height variations which are liable to be produced by a force exerted on the sealing ring in its axis of revolution. At least one of the nestable elements is formed of expanded graphite and compressed with a constant ratio. The elements are then fitted within each other until a sealing ring of predetermined height is obtained.
