Abstract
A misalignment connector has a pair of hubs providing internal, opposed spherical surfaces loaded into engagement with an internal, metal sealing ring having a spherical, outer sealing surface, the hubs being constrained together to maintain loading of the seal ring over a range of angles of misalignment. The internal seal ring is initially retained in position with respect to one of the hubs and is shiftable for proper sealing and loading engagement by the hubs over the range of permissible misalignment. The metal-to-metal seal between the hubs and the seal ring is backed up by a resilient seal. The metal seal ring has an outer peripheral projection forming a connection for the retainer, and the projection is engageable by the hubs to angularly shift the seal ring during assembly.
