The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s.
A valve cover gasket is a crucial component of an internal combustion engine, as it seals the valve cover to the cylinder head, preventing oil leaks and ensuring the proper functioning of the engine. The 318 valve cover gasket is specifically designed for the Dodge 318 engine, which is a popular choice for many vehicles due to its reliable performance and durability. The material used in oil seals is also important, as it affects the seal's durability and resistance to chemicals and heatIn conclusion, valve cover gaskets, head gaskets, and spark plugs are essential components in automotive engines, contributing to the efficiency, performance, and reliability of the engine. Understanding the significance of these components and their proper maintenance and replacement is crucial for optimizing the performance and longevity of the engine.
By first finding out the dimensions of the inner and outer diameters and the height of the bore, you have all the data for the correct size of the oil seal. Of course, the oil seal must also be able to withstand the pressure, temperature and medium it is exposed to within the seal during the manufacturing process. You can read more about this in our oil seal selection guide.
Standard 3760/3761
Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fitting
Finding oil spots under a parked vehicle can be both worrying and stressful for any vehicle owner. If the seal’s leak is small, oil may start to accumulate on the underside of the engine. But as the leak gets bigger, the oil leak will become visible in the front side of the engine.

Moreover, advancements in technology have led to the development of specialized oil seals with tailored compositions. For instance, seals with higher rubber content for increased flexibility in extreme temperatures, or those with reinforced metal components for enhanced durability in high-pressure applications. 2. **Industrial Equipment** Oil seals are used in a wide range of industrial equipment, from pumps and compressors to hydraulic systems. Incorrectly sized oil seals can lead to system failures and safety hazards. Understanding oil seal dimensions helps ensure the proper selection and installation of seals, maintaining system reliability and safety.
Another factor you need to consider is the type of lubricants that are more suitable for the seals. Check for the appropriate viscosity of the lubricant that’s compatible with the seal material.
PTFE Oil Seals - A relatively new and exciting oil seal, the use of polytetrafluoroethylene means that they can withstand dry or unlubricated operations. With a massive thermal range of -130ºC to +200ºC and a strong resistance to chemicals, they are considered to be the future of rotary shaft seals.
