4-1/2 ID 047 Buna-N O-Ring Pack of 10 Pack of 10 Black 4-5/8 OD 1/16 Width Small Parts 70A Durometer 4-1/2 ID 4-5/8 OD 1/16 Width
047 Buna-N O-Ring, 70A Durometer, Black, 4-1/2' ID, 4-5/8' OD, 1/16' Width (Pack of 10): O Ring Seals: Industrial & Scientific. 047 Buna-N O-Ring, 70A Durometer, Black, 4-1/2" ID, 4-5/8" OD, 1/16" Width (Pack of 10): O Ring Seals: Industrial & Scientific. This O-ring is made of black Buna-nitrile, is round in cross-section, has a durometer of 0A, and is designed for use in a wide variety of sealing applications. 。Buna-nitrile can have high tensile strength, and abrasion, tear, and compression set resistance. It can be used in temperatures between -30 degrees F (-34 degrees C) to 250 degrees F (2 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 weathering and should therefore not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light. 。This Buna O-ring has a shore durometer of 0A. Shore durometer is the hardness of a material, and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 00, with 00 indicating no indentation. 。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. They are circular in shape, with a round cross section, and a hole in the center, similar to a doughnut. O-rings are available in various sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter. 。These Buna-nitrile O-rings meet standards defined by Aerospace Standard AS58A, which is the Aerospace Size Standard for O-rings. 。 。 。 。
