The fitting further comprises a plastic covering portion surrounding the neck portion and covering and conforming to an upper surface of the flanged portion and conforming to the upper annular rim. The body portion is formed from a plastic material having a higher tensile modulous and higher deflection temperature than the plastic covering portion which forms a fusion bond with the liner.
