Product Details
This Cometic Multi-Layer Steel (MLS) head gasket is designed for the Nissan RB26DETT engine with an 88mm bore. It's built with multiple layers of stainless steel for strength and corrosion resistance, and the outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions without needing extra sealants. The center layer is stainless steel and can be varied to achieve different thicknesses, with this specific gasket having a compressed operating thickness of 0.036 inches from its original 0.027-inch thickness.
MLS gaskets are a solid choice for high-output engines, whether you're pairing aluminum heads with an aluminum block or aluminum heads with a cast iron block. The multiple stainless steel layers provide increased strength and the ability to rebound, helping to manage the forces between different block materials. The Viton coating on the outer layers is designed to withstand high temperatures up to 482 degrees Fahrenheit and various sealing demands, ensuring a dependable seal.
