Cometic Nissan RB20 Head Gasket 1.3mm Thick - C4495-051

Cometic MLS RB20 Head gasket 80mm Bore 1.3mm Thick

Cometic Multi Layer Steel (MLS) Head Gaskets

• Provide maximum sealing performance for today`s high output engines and require no sealants
• Ideal for aluminum heads to aluminum blocks and aluminum heads to cast iron blocks withstanding the shearing force created by the two materials.
• No need to re-torque, the embossing design of the MLS gasket promotes an even clamp load across the sealing surface allowing for measurable reduced bore distortion

Cometic MLS Gaskets are comprized of multiple layers of stainless steel due to it`s increased strength, ability to rebound and resistance to corrosion.

The outer layers of the gaskets are embossed and coated on both sides with Viton - a flouroelastomer rubber based material that is heat resistant to 250°C /482ºF. Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes.

The center or shim layer is uncoated stainless steel.
