Claim:
A ring seal comprising: a sealing ring including an asymmetric body portion having, in an uncompressed state, axially-opposed and radially-offset seal beads, a radially outward portion, a radially inward portion, an axially outboard sealing surface, and an axially inboard sealing surface axially spaced apart from and opposite said axially outboard sealing surface, wherein the seal beads include an axially inboard seal bead contiguous with the axially inboard sealing surface and an axially outboard seal bead contiguous with the axially outboard sealing surface and disposed radially inwardly of the axially inboard seal bead; the sealing ring also including a frustoconical skirt extending axially away from the axially inboard sealing surface at the radially inward portion of the body portion and extending radially inwardly from the axially inboard sealing surface to define an inner diameter of the sealing ring; and a reinforcement ring carried at least partially in the sealing ring to distribute load across the seal beads, and including a radially outer peripheral portion, a radially inner peripheral portion, a first planar portion between the radially outer and inner peripheral portions, a second planar portion between the radially outer and inner peripheral portions and completely embedded in the sealing ring, a bend between the first and second planar portions and radially between the seal beads of the sealing ring and completely embedded in the sealing ring, and a frustoconical bend at the radially inner peripheral portion and completely embedded in the sealing ring.
