1. A composite elastomeric seal, comprising: (i) an outer U-shaped seal body, the body comprising a first extending arm and a second extending arm that defines a groove therebetween, the first extending arm having a contour which curves inwardly so that a first sealing lip is located at the proximal end of the arm, and a second sealing lip is located at the distal end of the arm, and the second extending arm having a contour which curves inwardly so that a first sealing lip is located at the proximal end of the arm, and a second sealing lip is located at the distal end of the arm; and (ii) an inner elastomeric seal located within the groove of the outer seal body, wherein the inner elastomeric seal swells upon exposure to a fluid causing the inner elastomeric seal to exert pressure upon the second sealing lips of the first and second extending arms of the outer U-shaped seal body.
