A fluid seal assembly for use in high pressure sealing applications. The assembly includes a seal with a rigid casing having a radial casing flange and an elastomeric seal body bonded to the casing. The assembly also includes an annular lip reinforcing ring, made from a low friction material. The ring has a trapezoidal cross-section with an inner cylindrical surface closely spaced from the shaft to be sealed, an outer end face directly contacting the inner end face of the casing flange, and a beveled surface engaging and supporting an air side surface of the elastomertc seal body. |
