Construction & Design:

This cylinder head gasket is meticulously crafted from multiple embossed layers of stainless steel, providing exceptional strength and flexibility. The outer layers are coated on both sides with Viton, a high-performance fluoroelastomer rubber known for its resistance to heat up to 250°C (482°F), oils, and other harsh chemicals. This coating ensures a reliable seal even under extreme thermal and mechanical stress.

The center shim layer remains uncoated stainless steel, allowing for precise thickness control and optimal sealing pressure. The embossed design enhances the gasket’s ability to conform to surface irregularities, preventing leaks and maintaining consistent compression. This construction makes the gasket ideal for use in engines where aluminum heads are paired with aluminum or cast iron blocks, effectively managing the different expansion rates of these materials.
