EMERGENCY GEAR EXTENSION AND AFTER ORBITING TO REDUCE FUEL LOAD, RETURN FOR A LANDING.  INSP FOUND THAT A (SWIVEL FITTING) IN MAIN HYD RETRACTION/EXTENSION SYS OF RT MLG HAD (DEVELOPED A LEAK).  INSPECTION OF SWIVEL FITTING HAD BROKEN/FAILED INTERNALLY, CAUSING LOSS OF HYD SYS PRESSURE AND FLUID CONTENT.  NEW SWIVEL FITTING WAS INSTALLED ON RAMP.
