Abstract

Electrically-heated hose assembly including a hose and a first and a second fitting. The hose is constructed as having a core tube, a pair of spiral wound wires surrounding the core, and a jacket surrounding the core tube. A first end of each of the fittings is within a corresponding end of the hose, with a second end of the fittings extending beyond the hose end. The wires are wound around at least a portion of the second fitting end of a corresponding one of the fittings.
