ABSTRACT:
A connector arranged for high pressure fluid carrying conduits comprises a central core having at least one fluid passage such as an integral bore, formed therein and an outer member surrounding the central core and being moveable relative thereto. The outer member comprising at least one segment having a fluid flow conduit and sealing means for the connector junction comprising an intermediate member, at least one static seal for non-moveable surfaces and at least one dynamic seal for relatively moveable surface.
A plurality of segments may be stacked on top of each other and held together by the application of a compression force on shoulders of the segments.
A relative rotational capability is preserved for the parts of the connector yet a more reliable and versatile connector is achieved in which the modular construction allows a variety of sizes to be offered more easily and cheaply and engineering tolerances can be more easily be met than with a single piece construction.
