<br /><br />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).<br /><br />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.<br /><br />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.<br /><br />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.<br /><br />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.<br /><br />Specifications:<br />Outside Diameter: 54mm / 2.13-inch<br />Inner Diameter: 47.8mm / 1.88-inch<br />Cross-Section Diameter: 3.1mm / 0.12-inch<br />Package Content: 20pcs x O-Ring
