These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
Types Of Motor Oil
NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.

Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.
What are Oil Seals?
Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.
Refit all pipes and wires, and the air cleaner. Start the engine and check for oil leaks.
