A FLUID FLOW CONNECTOR FOR CONNECTING CONDUITS CARRYING HIGH PRESSURE PRODUCTION FLUID, THE ARRANGEMENT COMPRISING A FIRST MEMBER CARRYING A CONNECTING END OF THE ONE OF THE CONDUITS, A SECOND MEMBER CARRYING A CONNECTING END OF THE OTHER OF THE CONDUITS, THE FIRST AND THE SECOND MEMBER BEING MOVABLE RELATIVE TO EACH OTHER, WHEREIN THE FIRST CONNECTING MEMBER HAS: A CENTRAL CORE (1) WITH A PLURALITY OF BORES (31) FORMED LONGITUDINALLY THEREIN; AND A PLURALITY OF PASSAGES (32) FORMED RADIALLY OF THE CORE (1), EACH RADIAL PASSAGE COMMUNICATING WITH A RESPECTIVE LONGITUDINAL BORE, A PLURALITY OF ANNULAR CHANNELS FORMED BETWEEN THE CONNECTING MEMBERS, EACH ANNULAR CHANNEL PROVIDING A FLUID FLOW PATH TO A RESPECTIVE RADIAL PASSAGE (32) IN THE CENTRAL CORE (1), AND MEANS FOR SEALING THE OR EACH ANNULAR CHANNEL AGAINST LEAKAGE OF THE HIGH PRESSURE PRODUCTION FLUID, WHEREIN THE SEALING MEANS (37) INCLUDES: A SEALING MEMBERACTIVATED BY DIFFERENTIAL PRESSURE, AND MEANS FOR SUPPLYING A BARRIER FLUID TO THE SIDE OF THE SEALING MEMBER WHICH IS REMOTE FROM THE PRODUCTION FLUID FLOW.THE CONNECTOR HAS CONSIDERABLE ADVANTAGES OVER THE PRIOR ART AS IT IS VERSATILE AND MORE RELIABLE THAN KNOWN CONNECTORS.(FIG 1)
