- Manufacturing oil seals begins with the selection of raw materials. High-quality rubber compounds, such as nitrile butadiene rubber (NBR) or fluoroelastomers, are commonly used due to their excellent resistance to oils and fuels. Metal components, typically steel or stainless steel, are also incorporated for reinforcement and durability. Some seals may also include PTFE (Teflon) for enhanced chemical resistance.

The rubber oil seals are made of nitrile rubber, hydrogenated butyronitrile rubber,

diesel spark plugs. This ensures that the fuel-air mixture is ignited properly and that the combustion process is as efficient as possible. This is important for diesel engines, which rely on precise combustion to generate power.
