Remflex Graphite Header Gaskets | Ford Coyote 5.0L V8 SKU: 4984

Remflex Graphite Header Gaskets for Ford Coyote 5.0L V8

Exhaust leaks are a common issue on Ford Coyote 5.0L swaps, especially in Early Broncos and other classic vehicles where custom headers, tight engine bays, and repeated heat cycling are unavoidable. Over time, this thermal cycling causes header flanges, exhaust manifolds, and even cylinder head exhaust surfaces to warp, making it difficult for conventional gaskets to maintain a seal.

Remflex Graphite Header Gaskets are built to solve that problem at the flange. Made from 100% flexible graphite and proven in 30+ years of industrial applications where temperatures routinely exceed 2,000°F, these gaskets crush and rebound to seal warped surfaces permanently—without shrinking, burning out, or requiring re-torquing.

• Standard 1/8-inch thickness with a built-in 50% crush to seal flange gaps up to 1/16-inch

• 30% rebound after crush maintains sealing pressure through heat cycles, eliminating re-torque requirements

• Rated for up to 3,000°F, far beyond any Coyote exhaust system temperature

• Flexible graphite construction will not burn out, shrink, or harden like traditional composite gaskets
