​

JIS B 2401 is a common Japanese O-ring sizing standard. The purpose of the table below is to define O-ring size identification codes (dash numbers), O-ring cross sections (CS), O-ring inside diameters (ID), and O-ring outside diameters* (OD) for all JIS O-ring sizes. 

* Please note that the O-ring outside diameter is typically used as a reference dimension and is not used to define the compliance of a standard JIS part.
