If you need our Excel version x-ring size chart, please send an email to: [email protected]. You can also refer to our AS568 O-Ring Size Chart which is issued by SAE International.

The specifications in the above table are defined as follows and are basically the same as standard o-rings.

ID = Inside Diameter
OD = Outside Diameter
CS = Cross Section

Outside Diameter = Inside Diameter + Cross Section * 2

OD = ID + CS*2
