A sealing ring is disclosed for radially sealing two coaxial surfaces. The sealing ring has an annular convolution with a first radially facing sealing surface and a pair of annular leg portions forming second and third radially facing sealing surfaces. Each of the leg portions are provided with an annular bend to increase the radial resiliency of the seal. In an alternate embodiment, each of the leg portions of the sealing ring has a pair of annular bends. In yet another embodiment, the sealing ring is constructed of a pair of plies or layers.
