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.
