Engineering reference tool
O-Ring Cross Reference — AS568, JIS & ISO 3601
Compare verified dataset entries by nominal ID, cross-section and OD. The tool distinguishes dimensional similarity from formal standards equivalence.
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.
Closest by ID + CS
The primary classification favors both inside diameter and cross-section. A close ID with a substantially different cross-section is shown separately.
Standard vs conversion
A millimetre conversion of an AS568 size is not automatically a metric, JIS or ISO designation. Standard codes and tolerances must be checked independently.
