Designed for use\nin a wide variety of sealing applications, this Buna-nitrile O-ring meet\nstandards defined by Aerospace Standard AS568A, which is the Aerospace Size\nStandard for O-rings. Buna-nitrile can have high tensile strength, and has\nabrasion, tear, and compression set resistance. It is compatible for use with\npetroleum, hexafluoroacetone (HFA), hexafluoro-2-butyne (HFB) and\nhydrofluorocarbon (HFC) fluids, vegetable oil, alcohol, acids, and aliphatic\nhydrocarbons. Buna-nitrile is vulnerable to acetone, ethers, esters, ozone,\nsunlight and weathering, and should not be used in ozone-generating electric\nmotors, welding equipment, or in applications with exposure to UV light. The\ndurometer hardness of this Buna O-ring is 90A. Durometers measure the hardness\nof a material and its resistance to permanent indentation. A higher durometer\nvalue indicates greater resistance to indentation. On a scale of 0 to 100, a\nvalue of 0 indicates that a sample was completely penetrated, while a value of\n100 shows no indentation in the sample. The letter following the number\nidentifies the shore scale, which is either shore A or D. Shore A is used for\nsofter plastics, while shore D is used for harder plastics. O-rings provide a\npressure and fluid seal between cylindrically shaped, overlapping mating\nsurfaces and are commonly seen in engines, faucets, flanges, valves, and\nvarious cylinders. They are circular in shape, with a round cross section, and\na hole in the center, similar to a doughnut. O-rings are available in various\nAS568A dash sizes, which is the standardized sizing for O-rings, and defines\nthe nominal inside diameter (ID), outer diameter (OD), and cross-sectional\n(CS) diameter of an O-ring.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eMade of Buna-nitrile (also called Buna-N) for use with a variety of fluids from petroleum to aliphatic hydrocarbons\u003c\/li\u003e\n         \u003cli\u003eDurometer (hardness) of 90A for resistance to penetration\u003c\/li\u003e\n         \u003cli\u003eRound cross-section to provide a seal between cylindrical overlapping surfaces\u003c\/li\u003e\n         \u003cli\u003eFor use across a wide temperature range from -30 degrees F\/-34 degrees C to 250 degrees F\/121 degrees C\u003c\/li\u003e\n         \u003cli\u003eMeets standards defined by Aerospace Standard AS568A\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Mr O-Ring","offers":[{"title":"Default Title","offer_id":43713255014580,"sku":"B0051XYZFM","price":100.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B0051XYZFM.jpg?v=1731565744","url":"https:\/\/auspowers.com\/products\/214-buna-n-o-ring-90a-durometer-round-black-1-id-1-1-4-od-1-8-width-count-of-50-pack-of-1-214-0-984-inches-1-1-4-inches-0-139-inches","provider":"AusPower Australia","version":"1.0","type":"link"}
