Abstract: An annular seal comprising a metallic ring having a cross section. The cross section includes an axially extending body portion having a radial width and an axial height. A spaced apart pair of sealing arms extend axially from the body portion, wherein each sealing arm includes a radially opposed arcuate sealing surface. The arcuate sealing surface may be convex, for example. The spaced apart pair of sealing arms are spaced apart a radial distance greater than the radial width of the body portion. A sealing system comprises a plurality of interconnected metallic rings wherein the body portion engages the sealing arms of an adjacent metallic ring.

Abstract: The present invention relates to a seal comprising an annular sealing body comprising a radially outer peripheral groove, an upper load concentrating projection, a lower load concentrating projection, a compression relief region extending from the center of the load concentrating projections to the radially inner edge of the seal, and a compression relief region extending from the center of the load concentrating projections to the radially outer edge of the seal. Additionally, aspects of the present invention relate to a seal retainer comprising a thin metal sheet comprising a seal retaining aperture comprising a reception lobe and a retention lobe; wherein the reception lobe has a diameter larger than the outer diameter of the seal to be retained therein, and the seal retaining aperture has a diameter larger than the minimum diameter of the arch portion of the outer peripheral groove.
