NBR (Acrylonitrile-Butadiene Rubber) is an elastomer that offers high resistance to mineral oils, fats, fuels, and waxes, but not to concentrated acids and certain chemicals. NBR seals are suitable for temperatures ranging from -30 °C to 100 °C and can withstand pressures up to 16 bar, and in special applications even up to 50 bar. They are ideal for applications in the oil and fuel industry.
