Dimensional cross reference
Metric O-Ring to AS568 Cross Reference
Enter a metric O-ring inside diameter and cross-section to compare the closest AS568 nominal sizes.
AS568 ↔ JIS ↔ ISO
O-Ring Cross Reference
Compare verified dataset entries by nominal dimensions. Results are classified by dimensional similarity, not as automatic standards equivalence.
Enter dimensions or choose a standard size.
Example
25 × 3.5 mm is close to AS568-214 by nominal dimensions, but a close dimension does not establish standard equivalence.
Use ID + CS
Inside diameter and cross-section are the primary dimensions used for a first-pass size identification.
Verify before ordering
Check drawing tolerances, groove dimensions, material, hardness, pressure and temperature before substituting a seal.
