Buna-N O-Ring Kit, 90A Durometer, 30 Sizes (Pack of 382) Product Features Product Description This O-Ring set is made of Black Buna-N, has a durometer of 90A, and includes 382 pieces covering 30 dash sizes. The rings have a Round cross-section and can be used across a wide temperature range from -40 degrees F (-40 degrees C) to 212 degrees F (100 degrees C). The rings come in a plastic storage case designed for organization and portability. Designed for use in a variety of sealing applications, this Buna-N O-Ring set meets standards defined by Aerospace Standard AS568A for quality assurance. The set includes the following O-Rings: 20 pieces each for dash sizes 006, 007, 008, 009, 010, 011, and 012; 13 pieces each for dash sizes 110, 111, 112, 113, 114, 115, and 116; 10 pieces each for dash sizes 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, and 222; 7 pieces each for dash sizes 325, 326, and 327. Buna-nitrile can have high tensile strength, as well as abrasion, tear, and compression set resistance. It is compatible for use with petroleum, hexafluoroacetone (HFA), hexafluoro-2-butyne (HFB) and hydrofluorocarbon (HFC) fluids, vegetable oil, alcohol, acids, and aliphatic hydrocarbons. Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight and weathering, and should not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light. The durometer hardness of this Buna-N O-Ring is 90A. Durometers measure 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, a value of 0 indicates that a sample was completely penetrated, while a value of 100 shows no indentation in the sample. The letter following the number identifies the shore scale, which is either shore A or D. Shore A is used for rubber, while shore D is used for harder plastics. O-rings 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 a round cross section, and a hole in the center, similar to a doughnut. O-rings are available in various AS568A dash sizes as well as Metric sizes. O-ring size is defined by the inside diameter (ID), outisde diameter (OD), and cross-sectional (CS) diameter.
