Cometic Subaru EJ25D-EJ251-EJ252-EJ253/EJ255 .032in MLS Cyl Head Gasket-100mm Bore

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket, designed for Subaru EJ25D, EJ251, EJ252, EJ253, EJ255, and EJ257 engines. It has a 100mm bore and a compressed thickness of .032 inches. MLS gaskets are built with multiple layers of stainless steel, offering increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that handles demanding sealing conditions and various surface finishes without needing additional sealants. This makes them a solid choice for both aluminum-to-aluminum and aluminum-to-cast iron block configurations, as they can manage the shearing forces between different metals.

The center layer of this gasket is uncoated stainless steel, which can be varied to achieve different thicknesses. The Viton coating on the outer layers is designed to withstand high temperatures, up to 482 degrees Fahrenheit (250 C), making it suitable for high-output engine applications. This construction helps ensure a reliable seal, even under significant stress.
