FAQ

What is the advantage of FPM compared to NBR?

FPM offers significantly higher resistance to temperature, fuels, oils and aggressive chemicals than standard NBR seals.

What does TC mean on an oil seal?

TC indicates a double lip design with a spring-loaded primary sealing lip and an additional dust lip for contamination protection.

Can this seal be used in gearboxes?

Yes. It is commonly used in industrial and automotive gearboxes where high-temperature and oil resistance are required.

Is this seal suitable for chemical environments?

Yes. FPM material provides excellent resistance to many industrial chemicals and aggressive media.

What is the purpose of the secondary lip?

The additional lip helps prevent dust, dirt and moisture from reaching the primary sealing area.
