A high pressure tube seal is provided including a rigid cylindrical tube having an elastomeric seal body molded to an outer surface of the cylindrical tube. The elastomeric seal body includes a pair of raised seal bead portions at opposite ends of the seal body and a pair of recessed groove portions adjacent to the pair of recessed seal bead portions. A pair of anti-extrusion rings are disposed in the recessed groove portion in the cylindrical tube and includes a radially outwardly extending annular portion disposed between a pair of recessed groove portions of the elastomeric seal body. The anti-extrusion rings provide increased pressure sealing capability as compared to conventional tube seal designs.
