About Small Parts KIT-JMN90-30 Japanese Metric O-Ring

This metric O-Ring set is made of Black Buna-N, has a durometer of 90A, and includes 391 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: 18 pieces each for JIS B2401 sizes P3, P4, P5, P6, P7, P8, P9; 14 pieces for P10A, P11, P12, P14, P16, P18, P20; 11 pieces for G20, G22, G25, G30, G35, G40, G45; 10 pieces for P22.4, P25, P26, P30, P32, P34, P36, P40, P48. 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.
