Purpose of an Oil Seal
- Overall, twin spark plug technology has transformed the automotive industry, providing drivers with more powerful, efficient, and reliable engines. By incorporating dual spark plugs per cylinder, manufacturers have been able to optimize combustion efficiency, increase engine durability, and improve overall performance. With these advancements, drivers can enjoy a smoother, more responsive driving experience while also reducing their carbon footprint.
1) Seal type
Oil seals come in a range of sizes ranging from 0 cm to 33 cm, and choosing the right size is critical to performance. The size of an oil seal is determined by the following dimensions:
The car head gasket, also known as the cylinder head gasket, is a critical sealing component in the engine that plays a pivotal role in maintaining the integrity of the combustion chamber. This gasket is designed to seal the cylinder head to the engine block, preventing the leakage of coolant, oil, and combustion gases. A properly functioning car head gasket is essential for ensuring optimal engine performance, preventing overheating, and maintaining the overall efficiency of the engine.
Shaft Hardness
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.
Extrusion and Nibbling
If the car has a manual gearbox , select first or reverse gear and put the handbrake full on. Otherwise, disconnect the battery and remove the starter motor .
The lip is specially designed to ensure the oil seal works effectively with the different forces that arise during rotation. Many different designs and materials are used, so countless types of oil seals are available. These are chosen according to the application; pumps, gearboxes, wheels, and many other rotating applications where fluids need to be sealed. They are used in a variety of sectors, such as the chemical industry, manufacturing, wind turbines, automotive sector, food industry, and more. Oil seals are used in nearly all sectors.


metal cased oil seals. They can be used with a wide range of oils, greases, and other lubricants, making them suitable for various industrial applications. Additionally, these seals can withstand exposure to harsh chemicals, extreme temperatures, and abrasive materials without compromising their sealing capabilities.
