Cometic Gasket MLS Head Gasket 0.040" – Multi-Layer Steel, Viton Coated Cometic Gasket MLS head gasket engineered for high-output engines. Manufactured from multiple embossed layers of stainless steel with dual-sided Viton® coating, this gasket offers a compressed operating thickness of 0.040" for reliable, repeatable sealing. Key Features Multi-Layer Steel (MLS) : Multiple stainless steel layers provide superior strength, rebound and corrosion resistance. Viton Coating : Outer layers coated with heat-resistant Viton (to 250°C / 482°F) for exceptional chemical and temperature durability. No Sealants Required : Precision construction eliminates the need for additional sealants during installation. Compatibility : Ideal for aluminum-to-aluminum and aluminum-to-cast iron applications; designed to resist shear between dissimilar materials. Customizable Core : Uncoated stainless steel shim center layer allows thickness variation and consistent crush control. Benefits Designed for motorsports and performance rebuilds, the Cometic MLS head gasket delivers maximum sealing under high cylinder pressures, improved longevity in harsh environments, and consistent performance across repeated heat cycles. Its Viton sealing faces maintain integrity against fuels, oils and coolant exposure. Applications: Performance engines, forced-induction builds, high-compression naturally aspirated motors, and any high-output powertrain requiring durable, leak-free head sealing.
