Abstract
A flexible conduit having a flexible inner tube of a polymer material, a flexible coil of wire received over said inner tube, a flexible outer jacket shrunk onto the coil, and couplings inserted into the ends of both the outer jacket and inner tube. Preferably, the outer jacket is attached to both the coil and the couplings by an adhesive. Preferably, the conduit is made by extruding the inner tube, wrapping the coil of wire around the tube as it is being extruded, telescoping the outer jacket over the coil and tube, inserting the couplings, and heating the outer jacket to shrink it into firm engagement with the coil and to initiate curing of the adhesive on the interior of the outer jacket.
