The fitting also includes a swivel nut having threads and wrench flats, where the swivel nut defines a swivel nut end adjacent the threads, and the swivel nut is disposed on the opposing axial portion of the stem. The fitting also has a metallic wave spring washer disposed upon the stem between the stem shoulder and the swivel nut end, and a ferrule for securing a hose to the hose fitting at the ridged axial portion of the stem. In some cases, an inner fitting is disposed in the conduit at the opposing axial portion of the stem, and an inner hose may be in the conduit and attached to the inner fitting.
