ATHENA (MLS) Multi Layer Gasket

Material

ATHENA MLS gaskets feature a combination of 3 to 5 layers made of different types of raw materials. The outer and inner layers are designed to perform at higher compression levels than stock configurations, with varying steel types based on engine requirements. These gaskets provide an even torque load across the sealing surface to compensate for any bore distortion, making them ideal 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 full hard material. 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 for engine coolant/oil fluids. These 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. Located around the combustion chamber, it allows the cylinder head and engine block to clamp tighter, preventing gas leaks and avoiding component distortion through quicker temperature equalization.

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 for engine coolant/oil fluids and meeting the demands of harsh environments. 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.
