COMETIC C9179F5 Primary Gasket – High-Performance Fuel-Resistant Engine Seal

The COMETIC C9179F5 Primary Gasket is engineered for long-term reliability and superior sealing performance in demanding engine applications. Manufactured from premium fuel-resistant materials, this gasket resists creep, cracking, and becoming brittle over time, ensuring consistent performance. Its design incorporates multiple gasket types to suit various application needs, including Extreme Sealing Technology (EST) gaskets with embossed steel covered by proprietary rubber or solid copper for exceptional sealing strength. The Multi-Layer Steel (MLS) construction features steel layers coated with Viton® and inner support layers, providing excellent durability and heat resistance. The CFM composite material combines a steel tang center laminated core that enhances heat tolerance while maintaining a long-lasting seal. Aluminum Foamette Material (AFM) gaskets incorporate an aluminum core with a chemically blown nitrile rubber coating, which eliminates the need for gasket sealer and simplifies installation. The Single-Layer Steel (SLS) gaskets use a stainless steel core with embossed surfaces to create a heavy-duty seal, ideal for high-pressure environments. Additionally, Viton® gaskets feature a stainless steel core with a thin coating of Viton rubber on both sides, delivering chemical resistance and reliable sealing. Made in the U.S.A., this gasket is a durable and dependable choice for engine rebuilds and repairs, ensuring optimal performance and long service life in various automotive and industrial applications.
