Features:
1. They are round in cross-section. For use across a wide temperature range from -4 (-20°C) to 212 (100°C).
2. Nitrile Rubber 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. 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. 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.
