Cometic Multilayer Steel (MLS) Gaskets are designed to provide the best possible seal, even on engines used in marine applications. 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, and the gaskets have excellent rebound characteristics. MLS Cylinder Head Gaskets reduce bore distortion but can still endure extreme cylinder pressures. Sold individually.

Features:
- Made from stainless spring steel
- Exceptional resistance to corrosive substances
- 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)
