Copper Gaskets With Good Jointing and Sealing Performance

Copper gaskets are commonly known as oxygen-free copper solid copper gasket. They are stamped from 1/4 hard, high purity, oxygen free copper stock.

The design of the gasket is an object used to seal the joint between two surfaces or objects in order to prevent leaks, corrosion or contamination in a system where the two objects being joined are not perfectly matched. In addition, copper is a very soft metal. This means it can provide a cushion or support between objects or parts in the system.

What's more, copper gaskets have good jointing and sealing performance which makes them widely used on engines and flanges.

  • Superior thermal conductivity. This feature stabilizes the head and block temperature.
  • Oil resistance.
  • Corrosion resistance.
  • 25% coefficient of elasticity.
  • High tensile strength. The tensile strength of copper is about 32000 psi.


  • Copper gaskets are used to mate two vacuum flanges together.
  • Engines. Copper head gaskets are the superior choice for blown, nitrous, turbo-charged and high compression engines. And the automotive and aerospace industries are the biggest consumers.
  • Pipelines.
