Mr. Gasket Exhaust Gasket Material

Mr. Gasket Performance Exhaust Gasket Material is a professional-grade bulk sheet solution engineered for fabricators, racers, and enthusiasts who need to create custom exhaust gaskets for virtually any application. Available in multiple material compositions and sheet configurations, this product line delivers the flexibility to cut and trim gaskets to match any flange pattern or bolt configuration — no pre-cut gasket required.

Key Features:

• High-temperature resistant construction engineered to withstand the extreme heat demands of exhaust applications, with select composite variants utilizing an acrylic binder system for proven thermal resistance
• Multiple material options across the product line — including high-temperature composite and steel core/graphite-faced variants — to suit a wide range of sealing requirements
• Maximum torque retention helps eliminate gasket failure and keeps flanges sealed under pressure and through repeated thermal cycling
• Steel core stability on applicable variants provides structural integrity and outstanding resistance to blowout under demanding operating conditions
• Graphite facing on select variants delivers excellent thermal conductivity, helping transfer heat away from the mating surface for long-term sealing performance
• Conforms to minor surface irregularities for a reliable seal even on imperfect or lightly corroded mating surfaces
• High-recovery material maintains an effective seal even when the flange experiences a temporary loss of clamp-load
• Easy to cut and trim — the bulk sheet format enables custom fabrication for modified ports, one-off builds, prototypes, and non-standard configurations
• Suitable for OE replacement, high-performance street, drag race, and oval track applications
• Legal for use on emissions-controlled vehicles, uncontrolled vehicles, and racing-use-only applications
