Product Details

Mr. Gasket Copper Seal Header Gaskets are engineered for extreme heat applications where standard gaskets fail. Manufactured from dead soft solid copper material at .043" thickness, these premium gaskets provide superior sealing performance for high-performance street vehicles, drag racing, oval track, and turbocharged engines.

Key Features:

  • Dead soft solid copper construction (.043" thick) conforms to minor surface irregularities for excellent sealing
  • .051" embossment around each exhaust port creates positive seal on uneven surfaces
  • Total gasket thickness of .094" provides optimal compression and durability
  • Withstands extreme heat conditions from turbochargers and high-performance engines
  • Reusable design outlasts conventional header gaskets

These copper header gaskets are ideal for applications where exhaust temperatures exceed the capabilities of standard composite or multi-layer gaskets. The soft copper material creates a gas-tight seal even on warped or slightly irregular header flanges, making them perfect for racing applications and turbocharged setups.
