Describe difference between mechanical seal and oil seal – Whether it is a mechanical seal or oil seal, it prevents the fluid seeping the liquid to other parts of the machine, or it keeps the rotating parts lubricated.
Remove all traces of the old gasket from the pump and engine, using a paint scraper if necessary.



NBR, also known as nitrile rubber or nitrile, is the most popular material for an oil seal because of its good resistance to many oils and greases, such as mineral grease and hydraulic oil. Depending on their composition, synthetic oils and greases, such as those based on glycol, can damage NBR rubber materials. Depending on the amount of glycol, a PTFE lip seal may be the best choice. NBR is also unable to cope with contact with acids and solvents. The rubber is suitable for oil and grease at temperatures from -35 °C to 100 °C.
When installing a 38x52x7 oil seal, it is important to ensure that the seal is properly lubricated and aligned with the shaft. This will help to minimize friction and wear, and extend the life of the seal. It is also important to regularly inspect the seal for any signs of damage or wear, and replace it if necessary to prevent oil leakage.
