Parallel Valve Cover Gasket

These valve cover gaskets replace the original cork gaskets that are standard on Lycoming engines. They are molded from high temperature silicone rubber and do not harden over time, so they can be re-used again and again. This hi-tech silicone rubber offers a much lower compression set, so it is superior at maintaining an oil-tight seal for the life of the engine.
Two types available: parallel valve or angle valve engines.

NOT FAA approved. For experimental aircraft only.
