Maintenance and Replacement of Oil Seals:
An effective way to ensure particles do not contaminate your oil seal is to store it in a container or sealed bag away from areas where dust and debris are prevalent. Resealable, heavy-duty plastics bags and bins are ideal for keeping your shaft seal protected.

OIL SEALS
The oil seal would seal one face against a rotating member and the other face to a stationary housing. It would prevent dirt from coming between the hub or shaft and the seal.
Selecting Quality Rubber Valve Cover Gaskets

thick rubber gasket. This makes them ideal for outdoor and harsh environment applications where other materials may deteriorate quickly. Additionally, rubber gaskets are non-conductive and can provide an effective barrier against electrical currents, reducing the risk of electrical hazards.

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:


These are comparable to type R and RST, except the outer case does not have a metal reinforcement ring. To compensate, the outside is not made of normal rubber, but a hard, heavy-duty rubber fabric. The advantage is that these types can be made in a split version. They are almost always produced to order, and made of NBR or FKM.
