Construction & Design:

The Cometic MLS gasket is constructed from multiple layers of high-grade stainless steel, each embossed to enhance sealing capabilities. The outer layers are coated with Viton, a premium fluoroelastomer rubber known for its exceptional resistance to heat, chemicals, and wear. This coating ensures a tight seal under extreme operating conditions while protecting the gasket from degradation.

The uncoated stainless steel center shim provides structural integrity and allows for precise thickness adjustments to accommodate engine tolerances. This multi-layer design enables the gasket to flex and rebound under thermal cycling, maintaining a consistent seal and preventing leaks caused by metal expansion and contraction.
