Abstract
Abstract A port baffle provides a simple system for the closure and sealing of a manifold gasket aperture. In a preferred form, the port baffle is made of a resilient plastic material, preferably a glass-filled nylon. A baffle is comprised of a pair of plate-like members joined together by mating post and socket connector elements integrally affixed to adjoining faces of the members. The mating post and socket connector elements provide a press-fit retention system, and in the preferred embodiment, each plate contains only one mating post and one mating socket connector element.
