Buna-nitrile can have high tensile strength, and abrasion, tear, and compression set resistance. It can be used in temperatures between -40 degrees F (-40 degrees C) to 212 degrees F (100 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 70A. 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 100, with 100 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 \u003c\/p\u003e\u003cp\u003eFree shipping on orders $50+. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43384532893905,"sku":"BW-B00M90B3MS","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/81VuBT35OeL_abd048b9-92b1-4c7f-84fd-c70b3a3611ef.jpg?v=1791876177","url":"https:\/\/belmontwarehouse.com\/products\/475-o-ring-buna-n-70a-durometer-26-id-26-1-2-od-1-4-width-black","provider":"Belmont Warehouse","version":"1.0","type":"link"}
