1.They are circular in shape, round in cross-section. For use across a wide temperature range from -30 degrees F (-34 degrees C) to 250 degrees F (121 degrees C).
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.This O-ring is made of black nitrile rubber, has a durometer of 50A, and is designed for use in a wide variety of sealing applications.
4.O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves, and various cylinders.
5.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.
