DICHTOMATK SEAL TO DIN3760 R21 015,00X024,00X05,00 WA NBR

The WA FKM is a single acting rotary shaft seal for rotating or pivoting shafts with optional protective lip sealing action (WAS) on the side facing away from the medium against dirt accumulation from the outside. The elastomer outer sheath provides good static sealing, good thermal expansion balance, e.g. in light-metal housings, better sealing with greater roughness and secure sealing for split housings as well as good static sealing with thin liquid or gaseous media. FPM is superior to the NBR materials for high temperature applications, high peripheral speeds and chemically aggressive media. The combination of FKM and the optional tension spring made of rust and acid resistant steel permits application in various aggressive media.
