Using the metric O-ring size chart to spec your seal
This chart lists common metric O-ring sizes—inside diameter (ID) and cross-section (CS) in millimeters—that fall outside any single formal standard yet share established tooling. Engineers and buyers searching for generic metric O-ring sizes, metric O-ring dimensions, or a metric O-ring size chart use it to match a groove or mating bore to a known ID/CS pair, confirm that tooling already exists, and avoid the lead time and cost of a fully custom mold.
Give us the ID, cross-section, and application and ARC manufactures the seal made-to-spec in your chosen compound—from NBR, EPDM, and FKM to silicone and HNBR—with material selected for temperature, pressure, and chemical exposure. As a US manufacturer certified to ISO 9001:2015 and IATF 16949:2016, we confirm tooling and return a fast, accurate quote so your build stays on schedule.
