Auto parts oil seals play a crucial role in the proper functioning and maintenance of vehicle systems. These seals are designed to prevent the leakage of lubricating oil and the ingress of contaminants, ensuring the integrity and efficiency of various components within the vehicle. From wheel hub oil seals to steering oil seals, these components are essential for the smooth operation and longevity of automotive systems.

Amongst the several applications of oil seals, these are the most common three applications – o-rings, spring seals, and lip seals.

Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.


PTFE is special in that a pre-tensioned spring is not required. This is because the material returns to its original shape when heated, also known as the shape-memory polymers (SMPs) effect. These oil seals are also supplied as integrated parts, where it only needs to be installed as one component.
