1. A multi-layered hot melt adhesive transfer hose, comprising:
a metal inner tube for transporting heated liquid hot melt adhesive and forming an impermeable barrier layer configured to prevent an ingress of oxygen from passing through the metal inner tube and into the heated liquid hot melt adhesive, whereby the impermeable barrier layer comprises a metal that forms the metal inner tube and is configured to prevent an ingress of oxygen from passing through the metal inner tube and into the heated liquid hot melt adhesive;
the metal inner tube forming a structural layer configured to withstand a fluid pressure;
an outer covering overlaying an exterior surface of the structural layer; and
a heater for maintaining the heated liquid hot melt adhesive at a set point, wherein the heater is adapted to be electrically coupled to a power source controlled to maintain the set point to about 450° F. or less for an extended period of time.
