The invention provides a novel improved packing element having the basic shape of a polygon with arches formed around the periphery by deforming the edge area in one direction and an area axially within the edge area to form arches projecting in the opposite direction and providing an axially located aperture. Such packing elements can be conveniently formed using a simple cutting and stamping operation.
