ATHENA Multi-Layer Steel (MLS) Gasket

Material
ATHENA MLS gaskets feature a combination of 3 to 5 layers made from different types of raw materials.

The combination of outer and inner layers is designed to provide superior standard compression performance, and the type of steel used can vary depending on engine requirements.
Athena MLS gaskets provide uniform clamp load across the entire sealing surface to compensate for any cylinder bore distortion.

The Athena MLS gasket is the ideal solution for both aluminum cylinder heads with cast iron blocks and aluminum cylinder heads with aluminum blocks.

Manufacturing process
Newly designed Athena MLS head gaskets are made from high-quality, high-strength 301 stainless steel.
Each layer is individually formed by state-of-the-art laser cutting and embossed with an optimized forming process.
Two layers of the head gasket undergo a stress relief process to significantly reduce stress induced by embossing.
After the stress relief process, a proprietary two-component polymer coating is applied, ensuring uniform coverage of the outer layers, without interruptions in the coating. This process ensures micro-sealing of engine coolant and oil fluids.

Athena MLS gaskets are tested and analyzed on engine test benches and in endurance tests.

Gas Stopper Technology

Gas Stopper Technology is a key factor in the design of competition MLS head gaskets. The stainless steel stopper layer incorporates an innovative active folding system that provides a high-pressure seal around the cylinder bore when the cylinder head is tightened. The gas stopper is located around the combustion chamber, allowing for a firmer fit between the cylinder head and the engine block, preventing gas leaks.

This also prevents component deformation due to faster equalization of their temperature. Benefits

Superior sealing properties under high pressure conditions

Increased elasticity and consistent load resistance

Optimized load balance

Improved engine performance

Increased durability

Proprietary coating technology

Our two-component polymer coating is applied after the stress relief process and ensures uniform coverage of the outer layers, without interruptions in the coating. This process ensures micro-sealing of engine coolant/oil fluids and meets the demands of various harsh environments.

The first layer is a high-temperature compound that conforms to surface irregularities of the engine block and cylinder head. (Typical MLS head gaskets require a 30 Ra surface finish, while Athena's seal surface finishes up to 60 Ra).

The second layer is easily removable and does not stick to contact surfaces when disassembling the engine.
