    Specifications:

    Manufacturer's Part Number:
    C5692-040

    Cometic Multilayer Steel (MLS) Gaskets are designed to provide the best possible seal for naturally-aspirated, boosted, or nitrous-fed engines. These head gaskets are made from 3 to 5 layers of spring stainless steel, offering a stronger base material than standard cylinder head gaskets. Viton-coated outer layers create a superior seal not available with other steel or copper gaskets. Cometic MLS Cylinder Head Gaskets reduce bore distortion but can still endure extreme cylinder pressures. Sold individually.

    Features
  • Made from stainless spring steel
  • Excellent rebound characteristics and corrosion resistance
  • Viton rubber coating (.001'' thick) is bonded to outer layer of gaskets
  • Designed to withstand serious cylinder pressures without machining for installation of locking wire

    Installation Notes
  • Not designed for use on engines with O-rings or receiver grooves
  • Always refer to the fastener manufacturer to determine accurate torque values
  • A surface finish of 50 RA (roughness average) or finer is recommended for proper gasket seal
  • Cometic Cylinder Head Gaskets go on dry because they're coated with a sealant (adding another sealer can hinder gasket performance)
