- The Importance of High Pressure Oil Seals in Industrial Applications
In addition to these standardised types, the following special types are also available:
PTFE Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.
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.
- However, the report also notes that the oil seal market faces several challenges, including the need for increased research and development to develop more efficient and durable sealing solutions, as well as rising raw material prices and trade tensions that could impact the supply chain.
BENEFITS OF OIL SEALS
Replace the sump drain plug tightly and refill the engine with the right amount and grade of oil.


Proper techniques and diligence during oil seal installation will result in what seems like an unremarkable situation – a component holding its lubrication. When something you’ve installed works effectively and quietly, you know you’ve done it right.
Aflas is created from fluoroelastomers (FKM), providing the following benefits:
This is a specific type of synthetic rubber that’s commonly used in o-rings, gaskets, oil seals, sterile & chemical resistant gloves, and other molded items. Viton has a high density and it possesses the widest temperature range of -40 degrees Fahrenheit to more than 400 degrees Fahrenheit. This is why it’s highly preferred as the best material for higher temperature applications.
