In conclusion, auto spark plugs, car spark plugs, and car iridium spark plugs are essential components in the ignition systems of vehicles, contributing to the efficiency, performance, and reliability of automotive engines. Understanding the significance of these components and their proper maintenance and replacement is crucial for optimizing the performance and longevity of the vehicle's ignition system.
Corteco is a well-known brand in the automotive industry, supplying top-quality oil seals, including the first Simmerring® in 1929. The range consists of more than 7000 gaskets and more than 6500 OE-quality shaft and valve stem seals.

Because the inner diameter of the oil seal must be stretched during assembly, it is necessary for the shaft to possess a ramped edge. The angle at which the ramped taper should be chamfered is 30° a 50°. If a flange or keyway is present on the shaft, it is best to use a bushing. The bore should also have a chamfer of 30° over at least 1 mm on the ramped side. Be sure to round off the edges properly in the process.

Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.
