    Abstract: A seal for static and dynamic sealing of a space between two surfaces. The seal includes 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 may have an annular recess extending around the circumference of the seal. When the radial inner surface is disposed about first surface, the seal 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 first surface, and the opposite axial end face is oriented toward and compressible against the second surface.
