ABSTRACT:
Provided is a co-axial hydraulic hose assembly having a co-axial hose coupling releasably joining an inner hose and an outer hose of the assembly in a fluidly sealed engagement. The coupling construction comprises an end seal nut that securely fixes each end of the inner hose to each respective end of the outer hose, but which may be removed so that the inner hose may be removed if it has ruptured. Thus, a ruptured inner hose may be removed and replaced with a new inner hose inside of the original outer hose, and then the end seal nut is replaced at each end of the hose assembly to secure the two hoses releasably together in a fluidly sealed engagement, thereby allowing for continued use of the repaired co-axial hose. Optionally, the co-axial hose of the present invention may have a conduit disposed at the bottom end thereof in fluid communication with the annular passageway defined between the outer hose and the inner hose so as to drain fluid from the annular passageway in the event of rupture of the inner hose.
