ABSTRACT:
A seal of an elastomeric material used to mount an intake manifold in a gas-tight manner on the cylinder head of an internal combustion engine is disclosed. The seal is formed to blend together in one piece and is located in position on the side of the intake-manifold flange facing the cylinder head. The seal has sealing surfaces, which sealingly surround the periphery of the intake pipes of the intake manifold during normal operational use. The sealing surfaces are interconnected by web segments, and at least one of the web segments is designed in one area of its extent to act as a linear tolerance compensation segment, to be flexurally soft and/or capable of folding together.
