Abstract: A plastic component including a plastic body having a first body portion and an integral tubular portion defining a tubular extension and a lip seal on the tubular body, the plastic body being formed in situ on the lip seal. The method of making the plastic component including providing a first mold cavity having a portion for defining the body of the component and a communicating second cavity for defining the tubular extension, positioning an annular lip seal in the cavity defining the tubular extension, and injecting molten plastic resin in the first cavity and the second cavity to define the plastic component with the lip seal positioned on the tubular extension.
