The Cometic molded rubber thermostat housing gasket for GM Gen-4 small block LS is formed to the sealing surface and can be bonded to a carrier for added rigidity. Cometic develops and tests gaskets using in-house dynamometers and engine assembly rooms to ensure reliability. The molded rubber material resists swelling, cracking and brittleness and is intended to match the performance demands of modern engines in both street and track conditions.
