THE CREW FOLLOWED AIRCRAFT OPERATIONS MANUAL VOLUME 1 AND DE-SELECTED BLEED 1 AND WAITED 3 MINUTES, THE FAULT REMAINED.  THE CREW DE-SELECTED THE NR 2 BLEED SWITCH AND WHILE WAITING THE 3 MINUTES THE FAULT CLEARED.  THE CREW ELECTED TO RETURN TO MIA.  THE CREW DECLARED AN EMERGENCY AND LANDED WITHOUT INCIDENT.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  FOUND O-RING DAMAGED IN BLEED AIR TUBE UNDER CARGO FLOORBOARD NR 272AF.  REPLACED O-RING PER AMM 36-11-10.  THE OPERATIONAL CHECK WAS GOOD.
