Mr. Gasket’s MLS Head Gaskets Handle Extreme Cylinder Pressure


  • Multi-layered steel (MLS) construction features Viton-coated spring steel
  • Proprietary polymer coating seals surfaces twice as rough as a typical MLS gasket.
  • Soft radius embossment in the formation process improves conformability and reduces stress points
  • Stress relieving tempering process increases flexibility
  • Each MLS Head Gasket comes with an industry-leading lifetime warranty


CLEVELAND (April 14, 2015) – Performance automotive manufacturing company, Mr. Gasket, today announced its complete line of high quality Multi-Layered Steel (MLS) Head Gaskets for a wide range of domestic engines. These gaskets provide improved protection for high-compression, turbo and supercharged applications and deliver a tight, leak-proof seal under the most extreme conditions.

GasketThe gasket layers are individually cut using a state-of-the-art laser cutting process for precision tolerance. During the assembly process the gasket is soft radius embossed to provide additional protection in critical areas. This technique provides uniform clamp load distribution across the engine block deck and reduces stress points.


All Mr. Gasket MLS Head Gaskets go through a unique process after forming to reduce forming-induced stress points. The stress reduction process reduces brittleness in the materials increasing flexibility and deformation retention. A proprietary polymer is then applied to complete the gasket and ensure uniform coverage of the outer layers. A typical MLS gasket requires a smoother surface finish (30 Ra), but the coating on Mr. Gasket’s MLS Gaskets will seal a surface twice as rough (60 Ra). Each head gasket comes with an industry-leading lifetime warranty.


Mr. Gasket MLS Head Gaskets are available from $99.95 at retailers nationwide and online. For more information on Mr. Gasket’s MLS Head Gaskets, or the company’s complete line of high performance products, please visit
