Description: Metric O-Ring Kit, Buna-N, Black, 90A Durometer, 30-Sizes (Pack of 386 Pieces) Made of Buna-nitrile for use with a variety of fluids and hydrocarbons and has a durometer (hardness) of 90A Kit includes 386 pieces covering 30 metric sizes Plastic case for portability and organized storage For use across a wide temperature range from -40 degrees F (-40 degrees C) to 212 degrees F (100 degrees C) This metric O-Ring set is made of Black Buna-N, has a durometer of 90A, and includes 386 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. The set includes the following O-Rings: 16 pieces for metric sizes (cross section x inside diameter) 2x3, 2x4, 2x5, 2x6, 2x7, 2x8, 2x10; 13 pieces for 2.5x10, 2.5x11, 2.5x12, 2.5x14, 2.5x16, 2.5x17, 2.5x19; 12 pieces for 3x19, 3x20, 3x22, 3x24, 3x25, 3x27, 3x28, 3x30, 3x32, 3x33, 3x35, 3x36, 3x38; 9 pieces for 4x38, 4x41, 4x44. 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.
