ABSTRACT:
A connector assembly for connecting hydraulic lines in a control stab module assembly has an inner annular ring (27) having a plurality of radially outwardly facing ports (28) for the passage of hydraulic fluid therethrough, and an outer annular ring (1) having a plurality of radially inwardly facing ports (2) for the passage of hydraulic fluid therethrough. The inwardly facing ports (2) are arranged to be aligned with the outwardly facing ports (28) when the outer ring (1) is positioned about the inner ring (27). Each port comprises a first valve member (16, 33) which is resiliently biassed to a closed position to close the port, and urging means (53) are provided to urge the first valve member (16, 33) into an open position against the biassing means (17, 33) when said rings (1, 27) are positioned one about the other. Sealing means (25) are provided to seal an inwardly facing port (2) with an aligned outwardly facing port (28). Latching means for connecting the inner and outer rings (27, 1) are also provided.
