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","published_at":"2024-11-14T16:23:42+11:00","created_at":"2024-11-14T03:39:17+11:00","vendor":"Mr O-Ring","type":"O-Rings","tags":["industrial_Aug2024_update"],"price":11300,"price_min":11300,"price_max":11300,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":43713252327604,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B0051XYEGW","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"421 Buna-N O-Ring, 70A Durometer, Round, Black, 4\" ID, 4-1\/2\" OD, 1\/4\" Width (Pack of 5)","public_title":null,"options":["Default Title"],"price":11300,"weight":82,"compare_at_price":null,"inventory_management":"shopify","barcode":"421","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/auspowers.com\/cdn\/shop\/files\/B0051XYEGW.jpg?v=1731565727","\/\/auspowers.com\/cdn\/shop\/files\/51bid7qjm5L_862cb94d-7df9-46c0-af12-0dbfeb016442.jpg?v=1731515960"],"featured_image":"\/\/auspowers.com\/cdn\/shop\/files\/B0051XYEGW.jpg?v=1731565727","options":["Title"],"media":[{"alt":"[Australia - AusPower] - 421 Buna-N O-Ring, 70A Durometer, Round, Black, 4\" ID, 4-1\/2\" OD, 1\/4\" Width (Pack of 5) ","id":30960935600308,"position":1,"preview_image":{"aspect_ratio":1.941,"height":1319,"width":2560,"src":"\/\/auspowers.com\/cdn\/shop\/files\/B0051XYEGW.jpg?v=1731565727"},"aspect_ratio":1.941,"height":1319,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/B0051XYEGW.jpg?v=1731565727","width":2560},{"alt":"[Australia - AusPower] - 421 Buna-N O-Ring, 70A Durometer, Round, Black, 4\" ID, 4-1\/2\" OD, 1\/4\" Width (Pack of 5) ","id":30959413231796,"position":2,"preview_image":{"aspect_ratio":1.0,"height":1000,"width":1000,"src":"\/\/auspowers.com\/cdn\/shop\/files\/51bid7qjm5L_862cb94d-7df9-46c0-af12-0dbfeb016442.jpg?v=1731515960"},"aspect_ratio":1.0,"height":1000,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/51bid7qjm5L_862cb94d-7df9-46c0-af12-0dbfeb016442.jpg?v=1731515960","width":1000}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003e421 Buna-N O-Ring, 70A Durometer, Round, Black, 4\" ID, 4-1\/2\" OD, 1\/4\" Width (Pack of 5)\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eThis O-ring is made of black Buna-nitrile, is round in cross-section, has a\ndurometer of 70A, and is designed for use in a wide variety of sealing\napplications.
