Product Details

Mr. Gasket Copper Seal Header Gaskets are engineered to provide exceptional sealing performance in high-heat exhaust applications. Manufactured from dead soft solid copper material at .043 inches thick, these gaskets conform to minor surface irregularities to create a reliable seal between exhaust headers and cylinder heads.

Key Features:

  • Dead soft solid copper construction (.043" thick base material)
  • Embossed .051" ring around each exhaust port for superior sealing
  • Total gasket thickness of .094" (base plus embossment)
  • Conforms to irregular mating surfaces for consistent seal
  • Excellent heat resistance for extreme temperature applications
  • Ideal for high performance street, drag racing, oval track, and turbocharged engines

These copper header gaskets are designed specifically for demanding applications where conventional gaskets may fail due to extreme heat cycling. The soft copper material provides excellent thermal conductivity while maintaining a durable, leak-free seal even under the most challenging racing conditions.
