ABSTRACT:
A sealing device for sealingly connecting two coaxial conduits and the like of a conduit arrangement including a first conduit and a second conduit, wherein the second conduit is disposed a predetermined distance in the first conduit to provide between them an annular space adapted to receive the sealing device. The sealing device includes first projections and second projections, respectively, on the outer diameter and on the inner diameter whereby the projections on the inner diameter and the projections on the outer diameter are arranged at least in part in a common radial section of predetermined axial length. The outer diameter of the outer projections is greater than the inner diameter of the conduit having the greater inner diameter and the inner diameter of the projections arranged on the inner diameter of the sealing device are at most equal to or at least nearly equal to the outer diameter of the conduit having the smaller outer diameter.
