ABSTRACT:
An improvement of boss for a pressure vessel which has a plastic internal liner and a filament wound around outer shell and an opening at one end of the outer shell. The boss is made by pressing a metallic material and has a double wall neck projecting outwardly through the opening. The neck has an outside wall which extends radially at one end opposite the opening to form a flange embedded in the liner to form an air tight binding. The flange has an annular V-shaped notch ring in the upper surface and a plural number of protrusive stubs on the lower surface thereof to strength the binding with the liner for withstanding high pressure without leaking or rupture.
