    Abstract: Methods of making hose fittings include providing a stem having a fluid conduit, a first end, a second end with a raised shoulder, and a crimp region disposed between the first end and the second end. A swivel tube nut is placed over the stem, and the swivel tube nut is retained on the stem the by the raised shoulder. A ferrule is thereafter placed over the first end of the stem, and the ferrule comprises a partially formed hexagonal wrench surface, formed prior to. The ferrule is then crimped, at the hexagonal wrench surface, onto the crimp region of the stem.

    Abstract: Methods of making hose fittings include providing a stem having a fluid conduit, a first end, a second end with a raised shoulder, and a threaded region disposed between the first end and the second end. Further, the stem may include barbs for sealingly engaging an inner diameter of a hose. A swivel tube nut is then placed over the stem, and the swivel tube nut is retained on the stem the by the raised shoulder. A ferrule is thereafter placed over the first end of the stem, and the ferrule comprises a partially formed hexagonal wrench surface, formed prior to. The ferrule also includes female threads corresponding to male threads on the stem. The ferrule is screwed onto the stem and secured thereon via the hexagonal wrench surface.
