Description
The gasket is constructed from multiple embossed layers of stainless steel for increased strength, rebound, and corrosion resistance. The outer layers are coated with Viton rubber, which is heat resistant up to 482°F (250°C) and suitable for demanding sealing environments. This MLS design provides maximum sealing performance for high-output engines and does not require sealants, making it ideal for both aluminum-to-aluminum and aluminum-to-cast iron block configurations.
