Cylinder Head Gasket, M0115 Material, Blue PTFE Coated, Firering (th. 0.045") - Set of 5 pcs

This cylinder head gasket fits 3-1/2" cylinder bore engines. It is specifically developed for:Big Twin 84-99 (does not fit Twin Cam)XL1200 88-22 (does not fit XR1200 08-12) This gasket is made of MotorGasket M0115, a material developed and produced by Athena. MotorGasket M0115 consists of a central layer of steel, with asbestos-free material composed of a high percentage of aramid fibers, inorganic inserts, and NBR rubber as a binder on the sides.M0115 has good resistance to mechanical and thermal stresses and adheres well to surfaces. It is resistant to oils, fuels, water-glycol mixtures, and corrosion. It is suitable for cylinder head gaskets in internal combustion engines, intake and exhaust manifolds, and other applications subjected to high mechanical and thermal stress. The head gasket is a complex and crucial technological component. To meet the ongoing needs of the market, Athena conducts meticulous checks on its head gaskets, both during the design phase and during bench tests. Athena head gasket can be produced using different technologies, such as metal/elastomer combinations or multilayer with Athena steel and coating materials. Choosing a Top-quality gasket is the first step towards a reliable engine.Depending on the type, it is submitted to:1.1. High precision cuttingThanks to latest generation lasers, it is possible to obtain a high degree of precision and purity, completely eliminating production burrs. These can cause various elements (oil, water, compression gas) to infiltrate compromising engine operations.2.2. Alignment of reliefsThis solution increases the elasticity of the gasket during operation, guaranteeing excellent grip over time, even in extreme conditions. On the contrary, a misalignment of the reeds would cause an immediate flattening of the gasket, eliminating the function of elastic memory and the consequent loss of compression.
