FAQ

Why is FPM preferred over NBR?

FPM provides significantly better resistance to high temperatures, synthetic oils, fuels and aggressive chemicals than standard NBR compounds.

What does AO/TC mean?

AO/TC identifies a double lip rotary shaft seal featuring a primary spring-loaded sealing lip and an additional dust lip for improved contamination protection.

Can this seal be used in hydraulic pumps?

Yes. The AO/TC profile and FPM material are suitable for many hydraulic pumps, gearboxes and industrial rotating equipment where compatible operating conditions are present.

Is the seal resistant to synthetic lubricants?

Yes. FPM is highly resistant to most mineral and synthetic lubricants used in industrial machinery.

Where is this seal commonly installed?

It is commonly installed in gearboxes, electric motors, pumps, compressors, agricultural machinery and industrial drive systems.
