About Uxcell Nitrile Rubber O-Ring Assortment Kit 200

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, , 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.
