Why choose nitrile O-rings?

Nitrile elastomer, also known as NBR or Buna, is an economical elastomer which is extensively used in a variety of industries. They are good general purpose seals with some attractive properties, including:

  • Tear resistance
  • Wide temperature range (-50⁰C to 120⁰C)
  • Resistant to water, petroleum oils and some hydraulic fluids
  • Low compression set
  • Good abrasion resistance

Nitrile O-rings are particularly good at sealing against fats and greases at higher temperatures, as well as in environments where oils and petroleum based fluids are present. As a material, it’s used widely in agriculture, dairy industries, mining, plumbing, rail and automotive industries.
