Product Details

Mr. Gasket Copper Seal Header Gaskets are engineered to provide superior sealing performance in extreme temperature applications. Manufactured from .043" thick "Dead Soft" solid copper material, these gaskets offer exceptional conformability to seal minor surface irregularities commonly found on headers and exhaust manifolds.

Key Features:

  • Dead soft copper construction provides excellent thermal conductivity and durability
  • .051" embossment around each exhaust port for enhanced sealing on irregular surfaces
  • Total gasket thickness of .094" for optimal compression and sealing
  • Conforms to minor surface imperfections for leak-free exhaust sealing
  • Ideal for high performance street, drag race, oval track, and turbocharged applications
  • Withstands extreme heat conditions without degradation

These copper header gaskets are the preferred choice for performance enthusiasts who demand reliable exhaust sealing under the most demanding conditions. The dead soft copper material ensures the gaskets conform to both mating surfaces while maintaining excellent crush resistance and reusability.

This would require more skills that a cave man had but, I thought it was rather simple.

Easy check out. the new system is a lot better than the old one. Ability to reorder items is a good feature too. We do several thousands of dollars here a here and love to see the upgrades going through.

EASE OF PART SELECTION

good price easy to process

I enjoyed the fact that your website had a payment method linked with Amazon. I have never seen that before, but it was a great convenience!

GOOD SELECTIONS. NOT SURE WHEN I WILL RECEIVE ORDER

Hope this fits

Great, Thank you

so far so good
