An electrically conductive hose apparatus includes a hose having a wire reinforcer therein that is electrically conductive, an end section with some hose material being cut away to expose ends of the wire reinforcer; a hose end stem engaging the hose but not the wire reinforcer; a conductive ferrule sleeve clamped onto the exposed ends of the wire reinforcer; an insulated wire in electrical contact with the exposed ends of the wire reinforcer and the sleeve to form an electrically conductive circuit; and a rotatable coupling nut for rotatably connecting the hose and stem to a high pressure hydraulic system but that is insulated from the electrically conductive circuit. The apparatus can be used in an existing pre-approved high pressure hydraulic hose.
