Abstract:
1. A sealing ring having an upper surface and a lower surface comprising: a top bead disposed proximate the upper surface, wherein said top bead is tilted inwardly at a predetermined angle; a side bead disposed between said top bead and the lower surface, wherein a top portion of said side bead is tilted inwardly relative to an intake pipe, at a predetermined angle relative to an axial axis defined by the sealing ring, such that said side bead extends outwardly away from an outside edge of said top bead wherein only said side bead contacts an inside surface of the intake pipe; wherein said seal has a generally annular shape; wherein said top bead and said side bead are integrally joined, such that said side bead cooperates with said top bead to properly seal the intake pipe within a cylinder head; and wherein said side bead cooperates with said top bead to ensure said top bead remains flush against a surface of a wall when a force is exerted on said side bead, whereby said top bead and said side bead never overlap.
