Nitrile Butadiene Rubber O-rings

  • Good mechanical properties and high wear resistance NBR. Good resistance to many petroleum oils, greases, hydraulic fluids, alcohol, mineral oil, and grease.
  • Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight, and weathering and should therefore not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light.
