Valve cover gaskets are manufactured from a silicone rubber compounded especially for lubricating oil resistance and low compression set. It has a recommended temp. operating range of 67 to 446 F and will remain flexible while operating in the noted temp. range. One of the biggest benefits of replacing the factory cork gaskets with the Silicone rubber gaskets is that they are reusable and are easy to work with and are 1/8 thick silicone rubber.

This is a great product! Ill never use a regular valve cover gasket again. It is important to follow the correct torque settings when installing them. It is easy to over-torque. It would have been nice if the package included installation instructions, but I had them elsewhere. Beyond that, I can just say they are great, and I cant imagine why every airplane doesnt use them.
