Cometic Nissan E13S E15ET E15S E16i E16S E16ST .060in Head Gasket 77mm Bore Katherine Legges Indy 500 Double bid hit by early Ryan Hunter Reay crash. Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0. 060". Cometic MLS (Multi Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C 482 F). 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, which can be varied to accommodate multiple thickness requirements. Conforms load distribution across the sealing area Embossed Outer Layers Coated w Viton No sealants or re torque required Creates less bore distortion This Part Fits: Year Make Model Submodel 1982 Nissan 310 GX 1983 1984 Nissan Pulsar NX Turbo 1982 1983 Nissan Sentra Base 1982 1983 Nissan Sentra DX
