A seal assembly includes a support (146A), an outer seal (142A) extending circumferentially around a radially outer surface of the support (146A), and an inner seal (150A) extending circumferentially around a radially inner surface of the support (146A). In a more specific embodiment, the support (146A) comprises an annular base member (230A), an inner ledge (246A) extending from a radially inner side of the base member (230A), and an outer ledge (254A) extending from a radially outer side of the base member (230A) . The inner seal (150A) is disposed at a radially inner edge (242A) of the base member (230A) opposite the inner tubular member, and the outer seal (142A) is disposed around an outer peripheral surface of the outer tubular member. <IMAGE> |
