Nitrile (NBR) may be the most common elastomeric seal material for use in applications requiring oil resistance, durability and set resistance. Nitrile materials are compatible with most hydraulic media, including petroleum oils, water glycol, water/oil emulsions and many synthetics. A-8508 is an extended temperature grade material suitable for use from –54°C to +115°C (–65°F to +240°F). It has the lowest possible NBR temperature range and is well suited for use in Z seal lips, T seals and other products that must perform in cold weather. A-8508 also has a friction reducing agent to lower the coefficient of friction. NBR is not recommended for use where exposed to sunlight or ozone.
