Seal Oil Pan:
- Elastomers, such as nitrile, viton, and silicone, are often used for their resistance to various chemicals and temperature extremes.
Valve cover gaskets and head gaskets are essential components in automotive engines, serving distinct yet crucial roles in maintaining the integrity and functionality of the engine. The valve cover gasket seals the junction between the valve cover and the cylinder head, preventing oil leaks and contaminants from entering the engine. On the other hand, the head gasket seals the cylinder head to the engine block, ensuring the containment of combustion gases and the separation of oil and coolant passages.
- Oil seals serve as a barrier, preventing oil from escaping the confines of the machinery while also stopping contaminants from entering
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.
Before fitting the oil seal, it is essential to check that the oil seal, shaft and bore are clean and undamaged. The surfaces the oil seal will come into contact with must be free of sharp points or burrs. The sealing lip is fragile, so even minimal damage can cause a leak. It is also important that the shaft and bore are correctly finished.
- It can be modified for applications with large chemical exposure and hard vacuums.

In the mechanical world, where machinery and equipment make the earth move and gears rotate, the oil seal is an important component. Oil seals, or shaft seals, are a crucial part of various industrial equipment and applications, ensuring that lubricants don’t escape and contaminants don’t enter. While they may seem simple, their construction, design, and application are anything but. This in-depth guide aims to help you understand the essential role of oil seals, their construction, the various designs available, and key factors to consider when selecting one for your application.
