- To address this challenge, many companies have turned to advanced materials and innovative designs. For example, some seals are made from high-performance elastomers that can resist heat, cold, and chemicals better than traditional rubber compounds. Others feature intricate labyrinth patterns or multiple layers of protection to reduce the risk of leakage and wear.

PTFE Oil Seals
ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.

Factors in Oil Seal Selection
Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
