Cometic 1990+ Nissan 300ZX VG30DE/DETT 90mm .075 inch MLS-5 Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.075 inches and a 90mm bore, making it a solid choice for your 1990-1996 Nissan 300ZX with a VG30DE or VG30DETT engine. MLS gaskets are known for their strength and ability to handle the demands of high-output engines, offering reliable sealing performance without needing additional sealants. They are well-suited for applications where aluminum heads meet either aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metals.

The construction features multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are embossed and coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit (250 C). This Viton coating is designed to perform in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, allowing for adjustments to achieve different thickness requirements, like the 0.075 inches found in this specific gasket.
