A seal for a flange includes two separate sealing lips to seal the interfaces between the flange and the intake manifold and the cylinder head. One lip seals against the head surface when the flange is bolted to the cylinder head. The other lip seals around the intake manifold when the intake manifold, such as a tubular intake manifold, is inserted into the flange. The flange seal is made of elastomeric material, such as rubber, and is integrally bonded to the flange made of metal, such as steel or aluminum, during the molding process to form a flange seal having a one-piece construction. The flange seal also includes a gap between one of the sealing lips and an outer surface of the flange that provides a space for the displaced rubber to flow when compressed by the cylinder head. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
