Vauxhall / Opel Athena Multi Layer Steel Head Gaskets
Athena MLS Head Gaskets
Athena MLS Head gaskets are designed to suit the requirements of today’s competition engines offering enhanced sealing compared to the OEM product. The gaskets are assembled from 2-5 layers of high quality stainless and spring steels.
Thanks to their composition, Athena gaskets considerably increase the sealing and injection pressure to the lowest engine head bolt tension and guarantee better reliability and performance.
Athena MLS gaskets are manufactured from high grade 301 stainless steel. Each layer is individually formed using a state of the art laser cutter and embossed with an optimized formation process. All head gaskets go through a stress relieving process to significantly reduce forming induced stress.
All Athena gaskets receive a two part polymer coating applied after stress relieving to the outer layers providing no break in the coating. This coating ensures the micro seal properties of the gasket for engine oils / coolants and is able to withstand a variety of harsh environments caused by engine heat cycles.
Gas Stopper Technology
Athena Gas Stopper technology is a key design feature of Athena MLS gaskets. The stainless steel stopper layer features an “active fold” which delivers a high pressure seal around the cylinder bore when tightening the cylinder head.
The gas stopper / active fold is located around the combustion chamber, allowing cylinder head and engine block to clamp tighter helping to prevent gases leak from the combustion chamber.
