FAQ

Question?

What is the shelf life of this NBR seal with a cure date of 2016?

Answer:

According to DIN 7716 and ISO 2230 standards, NBR (Nitrile) seals have a recommended shelf life of 7 to 10 years when stored correctly (away from light, heat, and ozone). While this seal may still be functional, it is approaching the end of its recommended storage period and should be inspected carefully before use.

Question?

What does the ‘SL’ in the BAU2SLX2 designation mean?

Answer:

The ‘SL’ designates a ‘Schutzlippe’ or protective lip (dust lip). This is an additional, non-spring-loaded sealing lip that faces outwards to prevent dust, dirt, and other contaminants from reaching the primary sealing edge, thereby increasing the seal’s service life.

Question?

Is the 72 NBR 902 compound suitable for high-temperature applications or aggressive chemicals?

Answer:

72 NBR 902 is a standard Nitrile Butadiene Rubber compound. It has excellent resistance to mineral oils, greases, and hydraulic fluids. Its typical operating temperature range is -40 deg C to +100 deg C. For higher temperatures or aggressive chemical media like strong acids or ketones, a different material such as FKM (Viton) or FFKM would be required.
