Abstract
A seal assembly for a conduit connection including a first and a second conduit part, each having an axially extending flow passage and an end surface radially intersecting the flow passage. Each of the conduit parts includes an internal sealing cavity adjacent the end surface and radially off-set from the flow passage. A composite annular seal is interposed between the conduit parts and extends into the two sealing cavities. The composite annular seal includes a central rim portion from which extend two generally axially disposed lip portions projecting oppositely outwardly into the conduit sealing cavities, each lip portion having an annular groove therein. An elastomeric sealing member having a portion which mates with the annular groove in the lip portion of the composite sealing ring extends peripherally about each end of the lip portions and into conforming engagement with the internal sealing surfaces of the conduit parts. A clamping assembly is positioned about the conduit parts to draw them together and force the elastomeric sealing members to redistribute their volume and conformingly engage the internal conduit sealing surfaces.
