FAQ

What is the typical operating temperature range for the 88 NBR 101 material?

The 88 NBR 101 compound generally operates effectively in temperatures ranging from -30 deg C to +100 deg C, making it suitable for a wide range of standard hydraulic applications.

The AS profile is a standard wiper suitable for light to medium-duty applications. For heavy-duty environments with severe contamination, Freudenberg offers more robust profiles like the AUAS or P8 wipers, which feature a metal casing for better retention.

According to standards like ISO 2230, NBR-based seals (Group B rubbers) have a recommended shelf life of 7 years under proper storage conditions. With a cure date of 2021, this seal is well within its usable life.
