- Common Types of Oil Seal Dimensions
- Routine maintenance of your engine, including checking and replacing valve cover gaskets when needed, is essential to keeping your engine running smoothly and efficiently. By using high-quality gaskets, such as the 305 valve cover gaskets, you can prevent oil leaks and ensure that your engine is performing at its best.

PTFE Oil Seals
Cassette seals are designed to maximise grease or oil retention and protection against liquid or solid contaminants. These seals are provided with their own bushings in which dirt is kept out and oil/grease kept in by a multi-lip seal.
A wide range of sealing devices are used in various machines.
Sealing devices serve the following functions:
Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.

Prepare the shaft and prevent damage
Proper installation and maintenance of oil seals are essential to ensure optimal performance and longevity. Before installing a new oil seal, it is important to clean and inspect the shaft and seal housing for any damage or debris that could affect the sealing performance. Additionally, applying a thin layer of lubricant to the seal lip can help improve sealing efficiency and reduce friction during operation.
Set the gasket on the block and make sure that all holes are perfectly aligned before refitting the head (See How to remove a cylinder head ).
These problems can be overcome through a better understanding of the types of sealing materials available, redefined selection procedures and the consistent application of sound replacement and maintenance practices.
Variety of Oil Seals
The shaft on which the oil seal is mounted has to be ground to a rough surface finish. The shaft also should be hardened to prevent grooves forming on the shaft when the pressure is exerted by the spring on the seal. The area where the seal is fitted also has to be ground to prevent grooves that tend to wear out the lip of the oil seal faster than normal.
