Mr. Gasket Copper Seal Exhaust Gasket Sets

Mr. Gasket Copper Seal Exhaust Gasket Sets deliver superior sealing performance for the most demanding exhaust applications. Engineered from solid copper construction, these premium gaskets provide exceptional durability and heat resistance that outlasts conventional composite or steel gasket materials — making them a trusted choice for performance builds, heavy-duty towing, motor homes, and high-stress daily drivers alike.

Key Features:

• Solid copper construction for maximum heat conductivity, durability, and long-term reliability
• Embossed O-ring design creates a leak-proof seal directly at the exhaust port for a consistent, positive seal

• Maintains header bolt torque for a secure, long-lasting installation that stays tight over time
• Reusable design allows for multiple installations without sacrificing sealing integrity
• Conforms to irregular sealing surfaces, compensating for minor imperfections in headers, manifolds, and cylinder heads
• Ideal for performance engines, motor homes, towing vehicles, and other high-stress applications
