 –   Our silicone rubber gaskets are made from aerospace mechanical

      grade AMS  silicone and designed to withstand temperatures up

      to 400 degrees Fahrenheit.   

 –   Therefore, they will not break down and deform or crack up

      like cork or neoprene.   

 –   Our gaskets seal uneven and warped surfaces and 

      eliminate corrosion.

 –   Gaskets are 100% reusable.
