Technical Details

  • MLS (Multi-Layer Steel) Head Gaskets provide better heat transfer, little to no bore distortion and will tolerate high cylinder pressure applications Turbos, Superchargers and High compression. The outer stainless steel layers are coated on both sides with Viton (a fluoroelastomer rubber based material that is heat resistant to 250 C/ 482 F).
  • Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.
