The sealing ring is used on the telescopic fork and supports a clean seal in the fork area. This O-ring made of fluorine rubber FPM / FKM (commonly known as Viton) is temperature-resistant up to 200°C and therefore significantly more resilient than conventional NBR sealing rings. It offers outstanding resistance to oils, fuels and chemicals and is ideal for demanding applications with high temperatures or aggressive media.
