O-Ring Size Standard

SMS 1586 Metric O-Ring Size Chart

SMS 1586 is the Swedish metric O-ring standard, where each ring is identified by its inside diameter and cross-section — group D covers dynamic and static service, while group S is for static sealing only. Use this chart to match an ID and section to the right group, then ARC molds them to spec in your required compound.

Using the SMS 1586 chart to spec your O-ring

SMS 1586 is the Swedish metric O-ring standard, and engineers reach this chart when they need to match a ring by its inside diameter (ID) and cross-section (CS) rather than an imperial dash number. Each size is sorted into a service group: group D covers dynamic and static duty, while group S is intended for static sealing only. Whether you are cross-referencing an existing SMS 1586 metric O-ring, confirming a groove design, or searching for the right Swedish metric O-ring size, use the ID and CS columns to lock the geometry and the D/S group to confirm the ring suits your application.

Once you have the size, ARC molds SMS 1586 O-rings to spec in the compound your build demands — NBR, HNBR, FKM, EPDM, silicone, FFKM and more — matched to your temperature, media and pressure requirements. As a US custom manufacturer with 20 years of experience and ISO 9001:2015 plus IATF 16949:2016 quality systems, we tool to your exact ID, cross-section and tolerance and turn a fast, no-obligation quote. Send us the size and group and our engineers confirm the material, tooling and a clear path to production.

SMS 1586 Metric O-Rings

SMS 1586 refers to Swedish Mechanical Standard for o-rings (Sveriges Mekanstandardisering). In this standard, O-Rings are simply identified by ID and C/S, similar to DIN 3771. Additionally, all SMS 1586 O-Rings are classified into two groups. The first group, intended for dynamic and static installations is indicated in our table by the letter D. The second group, intended mainly for static applications, is indicated with an S.
