Cometic Honda Civic 1.7L D171 76mm .120 inch MLS Head Gasket D17

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer layer coated with Viton rubber. The compressed operating thickness is precisely 0.120 inches, and the bore size is 76mm, specifically designed for the Honda Civic's 1.7L D17 engine. MLS gaskets are known for their ability to handle the demands of high-output engines without needing additional sealants, making them a solid choice for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. They offer increased strength and corrosion resistance due to their layered stainless steel construction, which also allows them to rebound effectively under stress.

The Viton coating on the outer layers is a heat-resistant synthetic rubber capable of withstanding temperatures up to 482 degrees Fahrenheit (250 C), ensuring a reliable seal even in harsh operating conditions and across various surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, though this specific gasket is set at 0.120 inches. This construction helps manage the shearing forces that can occur between dissimilar metals, contributing to the gasket's overall durability and sealing performance.
