A dual hose arrangement for independently conveying two respective fluids is made rotatable, through unlimited 360 DEG excursions, at a situs near the ends of the hoses, in order to preclude twisting or kinking of the hoses when the end portions, which may include a multi-outlet nozzle, are handled. A first of the hoses contains a conventional swivel connection, permitting the end portion of the hose to be rotated without limitation. A fluid-tight box is mounted around the first hose, enclosing the swivel connection. The second hose is interrupted and terminated at ends of the box on opposite sides of the swivel connection so that the box couples the interrupted ends of the second hose and provides a conduit for the fluid carried by the second hose. The end of the box adjacent the ends of the hoses is rotatable with respect to the rest of the box so that when the ends of the hoses are twisted, the rotatable end of the box and the end of the first hose will rotate together about the axis of the first hose and the end of the second hose will rotate about the first hose. The arrangement is particularly suitable for use at the nozzle end of a gasoline hose which is paralleled by a second, vapor recovery hose.
