Valve Cover Gasket – Silicone

for

Pratt & Whitney R-2800-CB Series

–   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.
