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.

Common Mistakes to Avoid

Proper preparation is crucial for successful oil seal installation. Ensuring that the seal, shaft, and bore are correctly prepared and aligned prevents seal failure, leakage, and premature wear of the components.
