Moreover, the use of extension rods significantly enhances worker safety
Why is mechanical seal important in this situation? It is because the rotating shaft has to move in a wet environment, but there should not be the leakage of pressurized fluid. Hence, the role of a seal is quite critical.
- Skeleton oil seals are typically made of rubber or metal, with a spring-like structure that allows them to be flexible and adapt to the movement of the machinery. They are often placed in housing units or mounted directly onto the rotating part to ensure a tight seal.

- Leather Oil Seals – They are also known as Type L Oil Seals and are used most with parts that are subject to dirt and poor lubrication. They are pre-lubricated and can absorb fluids and can provide sealing properties in conditions that synthetic rubber is unable to.
Also, Viton has the widest range of resistance to chemicals. It’s resistant to several chemicals like silicone oil & grease, mineral & vegetable oil, aliphatic, chlorinated hydrocarbons, methanol fuels, and so many more.

Generally, an oil seal is made up of an outer circular metal part and a bonded inner flexible material (often nitrile rubber) that does the actual sealing.

What are Oil Seals and the different types?


The care taken during the installation process will pay off by allowing the seal to work quietly and operate efficiently behind the scenes of your application.
Different types of rotary shaft seals are available in the market, including radial lip, axial lip, and mechanical face seals.
