Description:

This O-ring is made from Buna-black nitrile, is round in cross section, has a durometer of 70A, and is designed for use in a wide variety of sealing applications. Buna-nitrile can have high tensile strength, and resistance to abrasion, tear, and established compression. It can be used in temperatures between -30 degrees F (-34 degrees C) to 250 degrees F (121 degrees C), and is compatible for use with petroleum, HFA, HFB and HFC fluids, vegetable oil, alcohol, acids and Aliphatic hydrocarbons. Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight, and erosion and therefore should not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light. This Buna O-ring has a 70A shore durometer. The shore durometer is the hardness of a material, and its resistance to permanent bleeding. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 100, with 100 indicating no indentation. O-rings commonly provide a pressure and fluid seal between overlapping and cylindrical shaped mating surfaces and are commonly seen on engines, taps, flanges, valves, and various cylinders. They are circular in shape, with a round cross section, and a hole in the center, similar to a donut. O-rings are available in various sizes and can be ordered based on Nominal Inside Diameter (ID), Outside Diameter (OD), and Cross Diameter (CS). These Buna-nitrile O-rings meet the standards defined by the aerospace standard AS568A, which is the aerospace size standard for O-rings.
