Exhaust Gasket Material Sheet 6.5in x 11in

The REMFLEX Exhaust Gasket Material Sheet 6.5in x 11in (SKU: REMGS16511) is a precision graphite exhaust gasket material engineered for high-temperature sealing applications in automotive and powersports environments. This half-inch by 6.5 by 11-inch graphite sheet provides the thermal resistance and compressibility required to prevent exhaust leaks at the manifold-to-head interface, where combustion temperatures and vibration demand materials that maintain integrity across repeated thermal cycling.

Constructed from graphite-based material 0.125 inches thick, this gasket sheet offers superior heat deflection compared to fiber composites, making it suitable for turbocharged or modified engines where exhaust temperatures exceed 1,200°F. The 6.5 by 11-inch dimensions accommodate most domestic and import exhaust manifold footprints, allowing technicians to cut custom gaskets for specific applications. Graphite composition resists blowby and maintains a consistent seal under pressure fluctuations typical of high-RPM operation, while remaining chemically inert to exhaust gases and combustion byproducts.

This material is essential for engine builders, shops performing turbo installations, and enthusiasts rebuilding exhaust systems on performance vehicles where OEM gaskets have failed or where custom manifold work requires dry-cut gasket material. Mechanics working on vintage muscle cars, modern turbocharged engines, or motorsports applications depend on materials like this to seal critical joints without risk of exhaust leaks that degrade performance and introduce unburned hydrocarbons.

Each sheet ships at 0.54 lbs and measures 6.7 by 0.55 by 11.15 inches, providing ample material for multiple gasket cuts or full manifold applications. REMFLEX gasket materials are recognized across the automotive aftermarket for reliability in extreme thermal conditions where standard gasket compounds fail.
