A non-pressure balanced fluid conducting swivel joint for coupling high pressure hydraulic conduit comprised of first and second tubular housing sections which are coaxially interfit with each other and a tubular sleeve member supported intervening between superposed portions of the housing sections. The sleeve is secured thrust resistant and for rotation to the inner of the housing sections via a pair of spaced apart annular races containing bearings extending between the inner housing section and the sleeve member. The outer housing is rotationally interlocked with the sleeve member by virtue of a flexible circumscribing pin engaging an insert contained in an annular groove complementary formed between the outer periphery of the sleeve member and the inner diameter of the outer housing. An external slot permits insertion and removal of the driving pin that includes a tang at its outer end which when the pin is operably contained in the groove can be removed for disassembly of the housing sections to effect servicing of the internal seal. An external sleeve when mounted about the slot of the outer housing serves to shroud the slot and tang from ready access so as to minimize tampering and potential environmental damage. |
