Seals

BMW Motorcycle ENGINE OIL SEALS 1951-1995 Except where noted these are Viton* seals with a coated outside diameter to help them seal in the bore. I suggest you avoid using the more commonly available Nitrile, as at operating temperature it tends to harden. *Viton is a registered trademark of DuPont Dow Elastomer
