Description

The Cometic C5497-120 is a Multi-Layer Steel (MLS) cylinder head gasket designed for high output engines. It features a compressed operating thickness of 0.120 inches and a bore size of 87.5mm.

The gasket is constructed with multiple embossed layers of stainless steel, with the outer layers coated in Viton rubber for heat resistance up to 250°C (482°F). The center layer is uncoated stainless steel. These MLS gaskets provide maximum sealing performance and do not require sealants, making them ideal for both aluminum-to-aluminum and aluminum-to-cast iron block configurations.
