AS568 O-Ring Chart References & Size Information

AS568 O-Ring Size Chart

The chart below represents all 369 as568 o-ring measurement sizes for both the cross section (CS) and inside diameter (ID). These sizes were published by the SAE (Society of Automotive Engineers) with the purpose to standardize o-ring sizes and dimensions. The original as568 o-ring sizes were published in 1971 and re-confirmed in 1974 as as568a. Both as568 and as568a are used interchangeably when referring to an o-ring dash size. To assist our customers in selecting the correct size o-ring we have included 3 measurements for cross reference purposes. Please note fractional dimensions are nominal, for more accurate measurements please refer to the actual inch or millimeter sizes.

• To calculate an o-ring's outside diameter (OD) you may use this formula: 2(CS) + ID = OD
• Conversely, if you have the OD and need to find the ID use this formula: OD - 2(CS) = ID
• To view stock and material availability please click on the coresponding dash number in the chart below.
