Multi-layered seal

A static or dynamic seal ring for installation within an assembly including a female part having a generally annular female part surface which extends along a central longitudinal assembly axis, and a male part having a generally cylindrical male part surface disposed in concentric opposition to the female surface, the part surfaces being radially spaced-apart to define a clearance gap therebetween, and the seal ring configured to be receivable in the gap coaxially with the assembly axis, the seal ring comprising an elastomeric body having a radial inner end defining a radial inner surface, a radial outer end defining a radial outer surface, a first axial end face, and a second axial end face, the radial inner end having a width narrower than the width of the radial outer end,

• the seal, when its radial inner surface is disposed about the male part surface, is rollable about an edge of the radial inner end such that one of the first axial end face and the second axial end face is disposed against the male part surface, and the opposite axial end face is compressible against the female part surface.
