[Size] - 22mm Outside Diameter, 18mm Inner Diameter, 2mm Cross-Section Diameter [Hardness] - 70A Durometer (Shore Hardness) for resistance to penetration [Nitrile Rubber] - Standard Nitrile Butadiene Rubber with a wide temperature range from -4℉ (-20°C) to 212℉ (100°C). The o rings has smooth surface, great oil and heat resistance, wear-resistant and good sealing performance [Application] - These small rubber o rings are widely used for automotive, pressure washer, filter, pump, water hose, plumbing pipe, engines, valves, air conditioning maintenance and much more [NOTE] - Please confirm the required size and material before purchase, and put it in the right place Description:

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 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 , faucets, flanges, valves, and various cylinders.

5.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 light.
