Abstract
An expansion coupling, for connecting a first conduit to a second conduit, has a housing that is open at opposite ends thereof. The conduits and at least one end of the housing have sealing means that comprise an interior sealing ring and an exterior sealing ring that has a larger external and internal diameter than the interior sealing ring. The interior sealing ring has a radially inwardly directed sealing surface and the exterior sealing ring has a radially outwardly directed sealing surface. The sealing rings have sealing side surfaces for sealing against adjacent sealing rings and the sealing rings are radially displaceable with respect to each other to accommodate for any misalignments of connected conduits.
