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.
- In addition to their robust construction, metal oil seals are also effective at maintaining a tight seal over long periods of time. This is achieved through the use of precision engineering and tight tolerances to ensure that there are no gaps or leaks in the system. As a result, machinery and equipment can operate smoothly and efficiently without the risk of oil leakage

Rubber gaskets, commonly used in various industrial applications, serve the purpose of preventing oil leakage and maintaining the integrity of machinery by creating a barrier between two or more components.
Nitrile rubber offers good durability for general use, while the flexibility of the spring behind the sealing lip keeps the oil seal firmly in place against the moving part.
