How to choose the material of the cylinder head gasket?/WTA BRAND

The selection of the material for the cylinder gasket needs to consider the engine operating conditions sealing requirements, and cost comprehensively. Metal gaskets (such as multi-layer steel, copper) are resistant to high temperatures and high pressures, suitable for turbocharged or-performance engines, but require high installation precision; composite material gaskets (graphite/non-asbestos fiber) have good elasticity and cost performance, suitable for ordinary aspirated gasoline engines; rubber/silicone gaskets are only limited to low-pressure sealing, such as cooling pipelines. Key factors: 1. Temperature and: select metal (such as multi-layer steel) for high temperature and high pressure; select composite material for medium and low temperature. 2. Sealing strength: use metalasket for combustion chamber, and composite material for oil and water channels. 3. Durability: for high-performance engines, it is recommended to use brand multi-layer steelasket, and ordinary cars can use graphite gasket. Summary: match the material according to the type of engine (family car, modified car, diesel engine), attention to the heat resistance, sealing performance and economy, ensure that the surface is flat during installation, and operate according to the specifications.
