The rings have a Round cross-section and can be used across a wide temperature range from-67 degrees F (-55 degrees C) to 257 degrees F (125 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 EPDM 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. Ethylene propylene diene monomer (EPDM) is compatible for use with water and steam, silicone oil and grease, polar solvents (alcohols), acids, glycol-based brake fluids, ozone, and weathering. It is vulnerable to many oils, gasoline, and solvents. This material meets ASTM International standards. The durometer hardness of this EPDM O-Ring is 70A. 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.

I used four of the smallest sized o-rings (-006) to fix my Mityvac vacuum pump (brake fluid was okay but hydraulic fluid did them in). When I get low on individual O-ring sizes in the future I will order replacements from McMaster-Carr if they are not available from Amazon.

Ordered another set then realized it was not dot approved so I ordered t hi is set only needed one o ring for clutch hydraulic line but I'm working in north dakota so supply is limited .shipping was fast the kit has many sizes so it will go in the tool box
