Gasket Terminology and Materials

MLS (Multi-Layer Steel) Exhaust Gaskets
Are designed for extreme cylinder pressures. MLS Exhaust Manifold Gaskets maintain a torque set and resist corrosion. They will not burn through or push out. MLS Exhaust Manifold Gaskets withstand different combinations of cylinder head and exhaust manifold materials. No sealants are required.
Valve Cover Gasket
Are manufactured from a soft durometer rubber wrapped around a steel torque limiting frame. Our valve cover gaskets offer unparalleled sealing and extended reusability. This design surpasses the quality and ability of a typical cork or paper gasket. The rubber and steel combination will withstand blowing out, over tightening, and high amounts of vacuum at an affordable price.
MLS (Multi-Layer Steel) Head Gaskets
Provide maximum sealing performance for today’s high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flouroelastomer 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.
LCE (Load Control Embossments)
LCE refers to a specific embossment design available on some MLS head gaskets. This embossment design requires less clamp load creating less bore distortion and conforms load distribution across the sealing area.

MLX (Multi-Layer Stopper)
Utilizes an integrated stopper layer for combustion chamber sealing and improved clamp load around the cylinder without increasing bore distortion. MLX technology can be found in some head gaskets and are made from the same materials as our MLS Head Gaskets. No sealants or re-torque required.
