Some disadvantages of NBR are poor ozone, sunlight and weather resistance as well as limited high temperature and flame resistance. For higher temperature resistance, a much better material to use is Silicone.
- In addition to their functional role, oil seals also contribute to the overall performance of the vehicle. By ensuring a consistent supply of lubricating oil, they help maintain the engine's smooth operation, reducing noise and vibration, and enhancing fuel efficiency.
Have you found the right oil seal for your application? The next step is fitting the oil seal correctly, so that it remains undamaged.
Entry of dust and debris is one of the most common reasons oil seals fail. For instance, in high-pressure applications, even the smallest sediments can create a gap in the seal, causing the oil to leak and dirt to get in.
The hydrodynamic ribsa) provided in two directions on the air side face of the lip ensure higher sealing performance (higher sealing performance in both rotational directions of the shaft). - E3 2012 attendees were treated to live demonstrations of this revolutionary spark plug in action.

Put the jack and wooden spacer under the sump and raise the engine just enough to free the supports.
Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.
These oil seals are the best for applications involving high temperatures. It’s suitable for temperatures between -4 degrees Fahrenheit and 392 degrees Fahrenheit. Also, it’s highly resistant to acids, dissolvent materials, and other chemicals. Viton (FKM/FPM) oil seals can run at a maximum speed of 38 m/s.

Use an old screwdriver or scraper to carefully remove all traces of the old gasket from the cover and engine flanges.
If the drive gear has slanting teeth, they may cause the rotor arm to turn. If it does, mark its new position to aid refitting
