The hose has an an armored crush-resistant outer layer and a heating layer disposed between an inner layer and an intermediate insulating layer. A pair of hollow tubular fittings have a beveled inflow to limit the amount of material which is out of the flow path as the material moves through the hose. The fittings have an associated pair of hose clamps.
