Air Intake Manifold Gasket

Cylinder Head Gasket

  • This multi layer steel gasket seals the cylinder head surface to the engine block, avoiding leakage of engine oil or coolant into the cylinders as well as external leaks.

    It is a critical sealing application of the combustion chamber which must withstand intense combustion pressure, hot engine coolant and oil. Consequences of the cylinder head gasket failing range from reduced power to severe engine damage.

    3M™ Dyneon™ Fluoropolymers help to avoid such problems due to their excellent resistance to engine oils and coolants even at elevated temperatures.

  • Expanded sealants made of PTFE with a microfibrillated internal structure for excellent stability are often used in flange sealing applications. This structure turns ordinary PTFE into a dimensionally strong, creep-resistant gasket material. The joint sealant is soft and conforms to worn or uneven surfaces. A melt adhesive strip holds the sealant in place for every assembly in the shop or field.
