Construction & Design

The Cometic MLS gasket is crafted from high-grade stainless steel layers selected for their strength, corrosion resistance, and wear durability. Its multi-layer steel design allows the gasket to flex and rebound, maintaining a tight, reliable seal even under extreme thermal cycling and elevated cylinder pressures common in VVT HEMI engines.

The embossed outer layers increase the sealing surface area, while the Viton rubber coating on both sides provides a resilient, heat-resistant barrier that adapts to surface irregularities on the cylinder head and engine block. This advanced construction ensures long-lasting performance and reliability, making it suitable for both OEM replacement and mild performance applications.
