Product Details

Mr. Gasket 7153 Copper Seal Header Gaskets are engineered for high-performance applications where extreme heat and sealing reliability are critical. These premium header gaskets are manufactured from dead soft solid copper material that conforms to minor surface irregularities, ensuring a leak-free seal between exhaust headers and cylinder heads.

Key Features:

  • Constructed from .043" thick dead soft copper for superior conformability
  • Total gasket thickness of .094" provides optimal sealing
  • Conforms to and seals minor surface imperfections on mating surfaces
  • Excellent thermal conductivity helps dissipate extreme exhaust heat
  • Superior durability withstands repeated heat cycles without failure
  • Ideal for high-performance street, drag racing, oval track, and turbocharged applications

The dead soft copper construction allows these gaskets to compress and fill microscopic gaps in header flanges and head surfaces, creating a gas-tight seal that resists blowout even under extreme cylinder pressures and temperatures. Perfect for serious performance enthusiasts who demand reliable exhaust sealing in demanding conditions.

Excellent service and fast shipping. A seller I would do business with again.

I ordered an AEM intake for my F-150 on Christmas day and received it on the 29th. I would absolutely recommend this site to anyone looking for car parts - they had the lowest price by far and shipped fast. Great job!

Great price!

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!

Great price and quick shipping!

Lowest price on the Internet, good packaging and fast shipping.

Excellent service!!!! Ordered another part from one of those big chain stores three days earlier and got your part one day sooner than theirs. Thanks. Excellent customer service. Wouldn't hesitate to use you again.

Great product and speedy service!

Couldn't be more happy with my product. I ordered from Autoplicity because they were the cheapest price around and I received my order within 5 days. I have installed the cold air intake and couldn't believe all the extra power. I am very pleased with the entire transaction.
