As you may have noticed, there are so many different markings for the different types of simulators, depending on the manufacturer. The KTT staff is always at your disposal to help you decipher the type designation in question.
Regardless of the material of the simulant (NBR, viton, i.e. FKM, silicone, i.e. MVQ, EPDM, HNBR or other), the type designations always refer to the design and do not vary for different types of material.
