ATHENA (MLS) Multi Layer Gasket

Material

ATHENA MLS gaskets feature a combination of 3 to 5 layers made of different types of raw materials. Outer and inner layers are designed to perform at higher compression levels than stock configurations, with steel types varying based on engine requirements. Athena MLS gaskets provide an even torque load across the sealing surface to compensate for any bore distortion. They are suitable for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

Manufacturing Process

Athena New Design MLS Head Gaskets are crafted from high-grade 301 stainless steel. Each layer is individually formed using state-of-the-art laser cutting and embossed with an optimized formation process. Two head gasket layers undergo a stress-relieving process to significantly reduce embossment forming-induced stress. A proprietary two-part polymer coating is applied after stress relief, ensuring uniform coverage of the outer layers and providing a micro seal of engine coolant/oil fluids. Athena MLS gaskets are tested and analyzed on engine dynos for endurance performance.

Gas Stopper Technology

Gas stopper technology is a key design factor of racing MLS head gaskets. The stainless-steel stopper layer features an "active fold" that delivers a high-pressure seal around the cylinder bore when tightening the cylinder head. This technology prevents gases from leaking out of the combustion chamber and avoids component distortion by equalizing the temperature of various components more quickly.

Benefits

• Superior sealing properties under high-pressure conditions
• Higher elasticity and constant load resistance
• Optimized load balance
• Improved engine performance
• Longer durability

Proprietary Coating Technology

The two-part polymer coating ensures uniform coverage of the outer layers, providing a micro seal of engine coolant/oil fluids. The first layer is a high-temperature compound that conforms to fill engine block deck surface and cylinder head surface irregularities. The second layer releases easily and will not stick to mating surfaces during engine disassembly.
