This FKM rubber piston seal fits the LC8 clutch slave cylinders of KTM, RSR Moto and Oberon. It is for the V twin engines. If you are installing the seal onto a KTM clutch slave cylinder, please make sure the seal is the same type as this one, with a groove, and not an O-ring seal.
This product is made of the same material as Viton seals, heat resistant FKM rubber. Their seal is green, ours is brown!
