Helically winding an extruded web to form a wall of a heated hose about a central axis, extruding a bead of plastics material around a heating wire such that the extruded bead comprises the heating wire at a first location within a cross-section of the extruded bead, helically winding the extruded bead onto the wall of the hose to provide a support helix, and exerting tension on the heating wire to draw down the heating wire toward the central axis such that the heating wire migrates radially inward from the first location to a second location within the cross-section of the extruded bead. Unwinding a portion of a support helix that comprises a heating wire from a wall of a hose at an end of the hose； sleeving a length of heatshrink tubing at least partly onto the unwound portion of the support helix； heating the heatshrink tubing to shrink onto at least part of the unwound portion of the support helix； and at an end of the unwound portion, directly connecting the heating wire to an electrical contact of an electrical connector. An undermold coupling to couple a hose to a hose fitting includes: a tubular portion to be inserted into a hose interface of the hose fitting； threads formed on an inner surface of the tubular portion to engage a support helix on an end of the hose as a set of threads； and a first grating comprising a first plurality of elongate portions to intermesh with a corresponding second plurality of elongate portions of a second grating of the hose interface, wherein the first plurality of elongate portions extend into a second plurality of slots defined by the second plurality of elongate portions, and the second plurality of elongate portions extend into a first plurality of slots defined by the first plurality of elongate portions.
