What does MLS construction mean for this head gasket?

MLS stands for Multi-Layer Steel. This construction uses several layers of steel to create a strong, durable gasket that can withstand high pressures and temperatures, offering a reliable seal for your engine.

What is Viton coating and why is it used on this gasket?

Viton is a type of synthetic rubber known for its excellent resistance to heat and oil. Coating the gasket's outer layers with Viton helps create a tighter seal against the engine block and cylinder head, improving durability in demanding conditions.

About this part

Product Details

This Cometic MLS head gasket is built with a .051 inch thickness and a 90mm bore, specifically made for the Nissan QR25DE 2.5L engine found in the 2002-2006 Altima, Sentra, and some Frontier models.

The outer layers of this gasket are embossed and coated with Viton, a high-performance synthetic rubber known for its resistance to heat and oil. This coating helps create a better seal against the engine block and cylinder head surfaces, especially under high temperatures and pressures. It's a well-built component designed to handle the demands of keeping your engine running smoothly.

When rebuilding the top end of your QR25DE engine, a reliable head gasket is crucial. This Cometic gasket is a solid option for ensuring a proper seal and maintaining engine integrity.
