Cometic Head Gasket Nissan Skyline 89-93 RB25 - C4317/C4318

Cometic Head Gasket Nissan Skyline GTR 89-93 RB25 The Cometic MLS gasket is compromised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, it's ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastometer rubber based material (viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 250 C or 482 F. The center or shim layer of the gasket is compromised of an uncoated stainless steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminium heads to cast iron blocks and aluminium head to aluminium blocks. The composition of MLS will also withstand the shearing forces creaed by aluminium heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion
