Description

Because of the technology available in today's high-performance engines, there came a demand for more durable head gaskets. Mr. Gasket responded to this challenge by creating the Ultra-Seal lineup. They feature excellent compressibility and high-temperature endurance, while not becoming brittle or brinelling aluminum cylinder heads. Their 5-layer composite construction sandwiches their patented Grafoil core material between two steel plates for strength, and a special elastomer coating is applied to both sides for leak-proof sealing protection. In addition, they're corrosion-resistant for compatibility with all types of fuel, and they won't require retorquing.
