Metric O-Rings Sized by Cross Section and ID

Metric O-Rings are sized by inside diameter and cross section in millimeters, making it easier to order the right seal without converting from inch sizes. This category includes Buna-N, Viton®/FKM, EPDM, Silicone, HNBR, FFKM, PTFE, urethane, encapsulated, X-Ring, JIS, ISO 6149 tube fitting O-Rings, and metric O-Ring kits. Customers use metric O-Rings for hydraulic fittings, pumps, valves, food equipment, chemical service, maintenance repairs, and imported machinery. Search by size such as 2.00X012 to quickly find available compounds and stocked options. For hard-to-measure seals, Olypsys® helps capture the ID and CS accurately, giving customers more confidence before they order.

Accurate O-Ring sizing starts with the right measurement. Small cross sections, large diameters, and worn or stretched O-Rings can be hard to measure with calipers or PI tapes. The Olypsys® Pro-Grid A4 uses AI powered vision measurement to quickly capture CS and ID, helping customers identify O-Rings with more confidence and less guesswork.
