Features:1. They are round in cross-section. For use across a wide temperature range from -4?? (-20 degreeC) to 212?? (100 degreeC).2. Buna-N or Nitrile has good mechanical properties when compared with other elastomers and high wear resistance. Good resistance to many petroleum oils, greases, hydraulic fluids, alcohol, mineral oil, and grease.3. O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, flanges, valves, and various cylinders.4. 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.
