ABSTRACT:
A flange seal molded as a single piece from a synthetic material which can withstand the high heat and pressure produced by the engine. The flange seal is shaped to correspond the intake manifold housing. Connecting portions on the flange seal separate the individual port openings. The flange seal is located between the intake manifold housing and the cylinder head to seal the joint. Pressure is applied to the flange seal when the fasteners are tightened to aid in sealing.
