Usually, these oil seals are used to seal lubricating oil or grease and contain it within the application, so that moving parts such as bearings are continually supplied with enough lubrication. However, such seals are also used for sealing other liquids, gases, and solids, such as powders or granules.
- There are several factors to consider when choosing truck spark plugs. The first is the type of engine the spark plugs will be used in. Different engines require different types of spark plugs to function optimally. For instance, diesel engines typically use larger, more robust spark plugs than gasoline engines. Additionally, the horsepower of the engine should be considered when selecting spark plugs. High-horsepower engines require spark plugs capable of handling the increased combustion pressures and temperatures.
High mileage oil is specifically designed for cars with more than 75,000 miles. This type of oil can help reduce oil consumption, minimize leaks and oil seepage, and can also help reduce smoke and emissions in older engines.
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
What are oil seals?
The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
If the seal is being fitted to original equipment you may have some influence over the shaft and housing bore finish, but if you are replacing a worn seal you still need to take into account the condition of these 2 essential parts.

Assembling the oil seal
In fact, modern and outstanding engine concepts require new and outstanding properties and solutions for dynamic seals, which continuously can withstand the high loads.
