{"v":"2.0","page_type":"product","title":"This metric O-ring is made of Buna-nitrile (also called Buna-N), round in cross-section, has a durometer of 70A, and is designed for use in a wide variety of sealing applications. Buna-nitrile can have high tensile strength, resistance to abrasion, tear, and compression set resistance. It is acceptable for temperature applications between -30 degrees F (-34 degrees C) to 250 degrees F (121 degrees C). It 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 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 cylinders of various sorts. 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 a number of sizes, and can be ordered based on required inside diameter (ID), outside diameter (OD), and cross-sectional (CS) diameter.","breadcrumbs":[{"label":"Home","href":"/python/html6/index.html"},{"label":"Brands","href":"/python/html6/menu_brand_index/menu_brand_index_brands_87101ba214.html"},{"label":"Small Parts","href":"/python/html6/menu_brand_products/1000/134000/menu_brand_products_SmallParts_1_19c565e850.html"},{"label":"AZ-N3.50X044.7/5","href":null}],"content":{"product":{"mpn":"AZ-N3.50X044.7/5","manufacturer":"Small Parts","brand":"Small Parts","brand_url":"/python/html6/menu_brand_products/1000/134000/menu_brand_products_SmallParts_1_19c565e850.html","title":"This metric O-ring is made of Buna-nitrile (also called Buna-N), round in cross-section, has a durometer of 70A, and is designed for use in a wide variety of sealing applications.
