Dual barrier seal

A sealed joint system, comprising:

• a first annular member and a second annular member each including opposing inner seal receiving grooves and outer seal receiving grooves, each of the inner seal receiving grooves including a radially inwardly facing first sealing surface and the outer seal receiving grooves including a radially inwardly facing second sealing surface;
• an annular dual barrier seal including a pair of axially extending inner seal lips and a pair of axially extending outer seal lips, wherein the pair of inner seal lips are connected to the pair of outer seal lips by a radially outwardly extending web portion, the pair of inner seal lips being received in the inner seal receiving grooves and the pair of outer seal lips being received in the outer seal receiving grooves, wherein the pair of inner seal lips extend axially by a first dimension and wherein the pair of outer seal lips extend axially by a second dimension which is greater than the first dimension, wherein the pair of inner seal lips have a sealing surface that is one of a partially toroidal surface of revolution generated by revolving a portion of a circle in three-dimensional space with a hole in a middle or partially non-spherically elliptical and that the sealing surface of the pair of inner seal lips engages the radially inwardly facing first sealing surface and the pair of outer seal lips have a sealing surface that is one of partially toroidal, partially elliptical, or conical and that engages the radially inwardly facing second sealing surface.
