Abstract:
A coupling for connecting a tube to a hose comprising:a metal tube having a main portion and an insertion portion, the insertion portion having an outer diameter corresponding to the inner diameter of the hose for insertion therein and a controlled inner diameter; a radial projection on the metal tube adjacent the insertion portion; a layer of plastic material covering the main portion of the tube and terminating at the radial projection, the radial projection being free of plastic material; a fitting having a bore therein slidably receiving the main portion of the metal tube, the fitting including an abutment surface extending radially of the bore and including an annular recess in which the radial projection on the tube seats; and an annular deformed portion adjacent the annular recess, which annular deformed portion is deformed into abutment with the radial projection to form a metal-to-metal fluid tight seal which also fixes the metal tube to the fitting.
