FAQ

'72' refers to the Shore A hardness of the material, which is a medium hardness suitable for many applications. 'NBR' stands for Nitrile Butadiene Rubber, a common elastomer known for its excellent resistance to mineral oils and greases. '902' is Freudenberg's specific formulation code for this NBR compound.

NBR material generally has a continuous operating temperature range of approximately -30 deg C to 100 deg C. For applications with consistently higher temperatures, a seal made from a material like FKM (Viton) would be a more suitable choice.

Always ensure the shaft and housing bore are clean and free of burrs. Lubricate the seal and the shaft with the system's operating medium. Use a proper installation tool that applies even pressure on the seal's outer diameter to press it into the housing. Never hammer directly on the seal, as this can damage the sensitive sealing lip and the metal case.
