Abstract: A swivel seal assembly is defined for providing sealed high pressure fluid communication between relatively rotatable generally coaxial conduits where dynamic runout and static misalignment may occur to one conduit relative to the other. A generally tubular washpipe is mounted in pivotally articulating relation to one conduit, and a generally tubular seal housing is telescoped over the washpipe and mounted in pivotally articulating relation to the other conduit. High pressure, staged rotary seals are supported by the seal housing and maintain bearing and sealing engagement with the washpipe so that the seal housing and washpipe articulate in unison in response to said static misalignment and dynamic runout, thereby virtually eliminating relative lateral motion between the seal housing and washpipe and minimizing rotary seal extrusion damage.
