  • Nitrile Back-Up Rings

    Nitrile Back-Up Rings
    See all 14 items in product family


    Nitrile rubber, also known as NBR or Buna N, is one of the most commonly used sealing elastomers due to its resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.
    • Acrylonitrile Content: The acrylonitrile (ACN) content of the polymer chains can be varied from 18% to 50%. Lower ACN content gives better low-temperature properties but poorer fuels and polar lubricants. Higher ACN content gives poorer low-temperature properties but improved fuels and polar lubricants resistance. Standard NBRs typically have 34% ACN content.
    • Cure system: Sulfur-cured
    • Standard Nitriles are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high temperatures.
    • Peroxide-cured nitriles have better heat resistance and lower compression sets but are more expensive and more difficult to process.
    Temperature Range:
    • Standard Low Temp: -40°C (-40°F)
