Type codes of some Freudenberg Simrit radial shaft seals
Converting seal types requires some basic knowledge. Indeed, there are so many different markings for the different types of simulators, depending on the manufacturer. Fortunately, the KTT staff is always at your disposal to help you decipher the type designation in question.
The type designation always indicates the version. This is true regardless of the material of the sizing ring. (For example: NBR, viton, i.e. FKM, silicone, i.e. MVQ, EPDM, HNBR or other materials.) Thus, they do not change for different types of material.
