Buna-nitrile can have high tensile strength, and abrasion, tear,\nand compression set resistance. It can be used in temperatures between -30\ndegrees F (-34 degrees C) to 250 degrees F (121 degrees C), and is compatible\nfor use with petroleum, HFA, HFB and HFC fluids, vegetable oil, alcohol, acids\nand aliphatic hydrocarbons. Buna-nitrile is vulnerable to acetone, ethers,\nesters, ozone, sunlight and weathering and should therefore not be used in\nozone-generating electric motors, welding equipment, or in applications with\nexposure to UV light. This Buna O-ring has a shore durometer of 70A. Shore\ndurometer is the hardness of a material, and its resistance to permanent\nindentation. A higher durometer value indicates greater resistance to\nindentation on a scale of 0 to 100, with 100 indicating no indentation.\nO-rings commonly provide a pressure and fluid seal between cylindrically\nshaped, overlapping mating surfaces and are commonly seen in engines, faucets,\nflanges, valves, and various cylinders. They are circular in shape, with a\nround cross section, and a hole in the center, similar to a doughnut. O-rings\nare available in various sizes, and can be ordered based on required nominal\ninside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter.\nThese Buna-nitrile O-rings meet standards defined by Aerospace Standard\nAS568A, which is the Aerospace Size Standard for O-rings.\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 and hydrocarbons\u003c\/li\u003e\n         \u003cli\u003eCan be used across a wide temperature range from -30 degrees F (-34 degrees C) to 250 degrees F (121 degrees C)\u003c\/li\u003e\n         \u003cli\u003eRound in cross-section to provide a seal between cylindrical overlapping surfaces\u003c\/li\u003e\n         \u003cli\u003eDurometer (hardness) of 70A for resistance to penetration\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":43713255473332,"sku":"B000FMWO1G","price":99.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B000FMWO1G.jpg?v=1731565772","url":"https:\/\/auspowers.com\/products\/234-buna-n-o-ring-70a-durometer-black-3-id-3-1-4-od-1-8-width-pack-of-10","provider":"AusPower Australia","version":"1.0","type":"link"}
