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 offer superior performance over standard compression, and the type of steel used can vary depending on engine requirements.
Athena MLS gaskets provide even torque load across the sealing surface to compensate for any cylinder deformation.

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 cylinder head gaskets are manufactured from high-quality, high-hardness 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 cylinder head gasket undergo a stress-relieving process to significantly reduce stress induced by embossing.
After the stress-relieving process, a proprietary two-component polymer coating is applied, ensuring uniform coverage of the outer layers, with no interruptions in the coating. This process ensures the micro-sealing of engine oil and coolant 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 racing MLS cylinder head gaskets. The stainless steel stopper layer incorporates an innovative active folding system that provides a high-pressure seal around the cylinder when the cylinder head is tightened. The Gas Stopper is located around the combustion chamber, allowing for a tighter fit between the cylinder head and the engine block, preventing gas leaks.

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

Superior sealing properties under high-pressure conditions

Increased elasticity and resistance to constant load

Optimized load balancing

Improved engine performance

Greater durability

Patented coating technology

Our two-component polymer coating is applied after the stress-relieving process and ensures uniform coverage of the outer layers, with no interruptions in the coating. This process ensures the micro-sealing of coolant/engine oil fluids and meets the demands of various harsh environments.

The first layer is a high-temperature compound that conforms to the 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 peels off easily and does not stick to the contact surfaces when the engine is disassembled.
