ABSTRACT:
A radiator overflow container for receiving liquid at pressures above atmospheric, including a plastic body portion and a cylindrical or tubular metallic orifice. The metallic orifice has first and second axial ends, and inner and outer surfaces which define an opening which extends between the first and second axial ends. The metallic orifice has the first axial end embedded in the plastic body portion with a plastic-to-metal interface which includes an annular plastic portion which extends into the opening to define an annular, plastic sealing surface. A radiator cap, engageable with the second axial end of the metallic orifice, includes a depending portion which extends into sealing engagement with the annular, plastic sealing surface, to place the plastic-to-metal interface outside the higher-than-atmospheric pressure operating enviroment of the radiator overflow container.
