Multi-Layer Steel gaskets are comprised of multiple embossed layers of both viton coated and uncoated stainless steel, requiring less clamp load, creating less bore distortion, and conforms load distribution across the sealing area.

The embossed outer layers of Cometic head gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The MLS Gasket (Multi-Layer Steel) features an active combustion seal on multiple layers.

MLX Gaskets (Multi-Layer-Steel-Stopper) features an extra 'stopper' fold-over layer providing a torque limiting surface that prevents yielding of the combustion seals. High temperature polymer along with embossments provide a micro seal for fluids against the head and block surface.
