Uxcell O-Rings Nitrile Rubber 36Mm X 44Mm X 4Mm Round Seal Gasket

Specifications:Inner Diameter: 36mm / 1.42-inchOutside Diameter: 44mm / 1.73-inchCross-Section Diameter: 4mm / 0.16-inch Package Contents: 1 x O-Ring Descriptions: 1. They are circular in shape, round in cross-section. For use across a wide temperature range from -4 (-20°C) to 212 (100°C). 2. Nitrile Rubber or Nitrile has good mechanical properties when compared with other elastomers and high wear resistance. Good resistance to many petroleum oils, greases, hydraulic fluids, mineral oil and grease. 3. This O-ring is made of black nitrile rubber, has a durometer of 70A, 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 flanges, valves, and various cylinders. 5. Nitrile rubber 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.
