Construction & Design

The Cometic MLX RHS Head Gasket is constructed using multi-layer steel (MLS) technology, which provides exceptional strength and flexibility to withstand high combustion pressures and thermal cycling. The embossed outer layers are coated with Viton, a high-performance elastomer known for its resistance to heat, oil, and chemicals, ensuring a long-lasting seal even under extreme operating conditions.

The gasket’s design incorporates HP shim technology, which enhances the clampload around the combustion chamber. This feature is critical for maintaining a tight seal on open deck blocks, reducing the risk of head gasket leaks and improving overall engine reliability.
