In fact, modern and outstanding engine concepts require new and outstanding properties and solutions for dynamic seals, which continuously can withstand the high loads.

Where loads are light, the outer skin layer can be made of silicone. It can be made of Fluroelastomer (orViton) to protect under high temperatures (more than 120 degrees Celcius). The skin can also be made of Poly Acrylate or Polytetra-FluroEthylene.
Viton (FKM/FPM) Oil Seals

Nitrile is the most widely used rubber (elastomer) and it’s recommended as the best for almost all standard applications. This is solely due to the fact that nitrile has some intrinsic properties, such as low cost and compatibility with most environments. Some of the general applications of nitrile are non-latex gloves, automotive transmission belts, footwear, gaskets, synthetic leather, hoses, o-rings, and oil seals.

Car Oil Seal Types and Applications


An overview of the different standard types of oil seals and their main characteristics is shown below.
Compared with nitrile rubber, superior in resistance to heat and abrasion
The reasons for the birth of this new generation of seals is that integrated oil seals reduce the manufacturing time of series production engines. Therefore, significant time savings are achievable when replacing the radial crankshaft seals.
