Designed and manufactured in Italy, the reinforced cylinder head gaskets from the brand Athena are available in two forms:

• MLS: these gaskets are made up of several sheets of stainless steel superposed and riveted together. The stainless steel sheets are laser cut for increased precision and receive an elastomer-based surface treatment (NBR or FKM). In order to obtain optimal sealing, the contours of the cylinders and water and oil passages are stamped/embossed. For the most extreme applications, reinforcement at the level of the cylinders is added.
• O-ring: these gaskets consist of a steel sheet covered with asbestos-free aramid fibre and an AISI 304 stainless steel ring (at the cylinder level). A bead of silicone applied to critical points (water and oil passages) ensures maximum sealing of the head gasket. This type of gasket is mandatory for heavily supercharged engines.
