Abstract: The present invention discloses a boss configuration for a Type IV composite pressure vessel (“CPV”). In particular, the invention provides liner-to-boss interface that allows the polymeric liner to wrap around the internal collar of the boss that extends below the flange. Since the wrap-around section of the liner conforming to the internal collar portion of the boss is subjected to pressure from all sides, the liner stays adhered to the boss when the inside surface of the liner in a CPV is subjected to internal pressure from the contained fluid.
