Product Details

Mr. Gasket Copper Seal Header Gaskets are engineered to deliver superior sealing performance in high-temperature 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 your headers and cylinder heads.

Key Features:

  • Dead soft solid copper construction (.043" thick base material) for excellent heat dissipation and conformability
  • .051" embossment around each exhaust port creates positive sealing on irregular surfaces
  • Total gasket thickness of .094" for optimal compression and sealing
  • Engineered for high-performance street, drag racing, oval track, and turbocharged applications
  • Withstands extreme heat conditions where conventional gaskets fail
  • Conforms to and seals minor surface imperfections for leak-free operation

These header gaskets are ideal for enthusiasts running high-performance engines that generate extreme exhaust temperatures. The copper construction provides superior durability compared to composite gaskets, while the embossed design ensures consistent sealing pressure around each exhaust port.
