About the SMS 1586 standard for O-rings

The SMS 1586 standard for O-rings is produced by the Sveriges Mekanstandardisering (Swedish Mechanical Standard). The SMS 1586 specification describes 140 O-rings in two different groups: dynamic and static.

The dynamic group describes 65 O-rings. Each size is designated by its dimension: ID × cross-section.

The static group describes 75 O-rings. Each size is designated by its dimension: ID × cross-section.

In contrast to the AS 568 A inch system, the nominal and physical dimensions of metric O-rings match precisely. That is, a mm O-ring will have a cross-section of mm. The space that is being filled must be about 10% to 15% smaller than the cross-section of the O-ring in order for O-ring to seal properly.
