Master O-Ring Size Chart
AS568 Size Chart
Metric O-Rings are sized by ID × CS in millimeters , not by an inch dash number. The
international standard is ISO 3601 . Drawings say things like 20 × 2.5 or 25 × 3 ;
on The O-Ring Store they appear as CS×ID codes such as 2.50X020.

Class A / AS568 Metric O-Rings are specified as ID × CS in millimeters .
Store codes use CS×ID (for example 2.00X010).
OD = ID + 2×CS. Code links open a product search on

ISO 3601 Class A (AS568-aligned) These ISO rows match the inch AS568 dash family (Class A interchange).
Prefer the dedicated

Common cross-sections include 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 5.7, 6.0, 7.0, and 8.0 mm .

ISO Class A sizes interchange with AS568 dashes. If the print says -214, use the
AS568 chart . If it says a mm size like 25 × 3.55,
use the tables above.
“Close” metric and inch numbers are not drop-in replacements. A near-metric ring in an
inch gland (or the reverse) can sit loose or over-squeeze.
Other size charts History and explanation of the ISO 3601 standard What ISO 3601 is ISO 3601 is the international fluid-power O-Ring family of standards. Part 1
(ISO 3601-1 ) is the size document: inside diameters, cross-sections, tolerances, and
designation codes for general industrial and aerospace sealing. Later parts cover housings,
quality appearance, back-up rings, and related guidance.
Like AS568, ISO 3601-1 is about geometry . Compound, hardness, and approvals still come
from a separate material callout.
Why it exists National size systems grew up separately—AS568 in the US, DIN in Germany, JIS in Japan,
BS in the UK, and others. As equipment and supply chains went global, the same “O-Ring”
ordered in one country often would not fit hardware designed in another.
ISO 3601 was created so fluid-power and industrial buyers could specify sizes in one
international language, primarily in millimeters .
Timeline (plain version) Year / edition What happened 1978 First ISO 3601-1 published. Early sizes tracked European (DIN-style) general-purpose metric practice more than US inch dashes. 1988 / 2002 Revisions added aerospace metric sizes and corrections, but still left a gap for the AS568 sizes used worldwide. 2008 Major rewrite. AS568 sizes , expressed in mm, entered ISO 3601-1. Class A and Class B tolerances were clarified. ISO 3601-2 published housing dimensions for general fluid-power use. Later editions Maintenance and updates to the multi-part series (sizes, housings, appearance grades, back-up rings).
Class A vs Class B Class In practice Class A Tighter ID tolerances; aligns with AS568 geometry. Use when the print or housing needs the same precision as the US dash system. Class B Wider (more economical) tolerances for many true metric industrial sizes and grooves.
That is why this handbook page lists preferred metric CS groups and also shows
Class A / AS568-aligned rows for people who measure in mm but still need the dash family.
How ISO 3601 relates to other charts on this site What ISO 3601 does not tell you It will not pick the elastomer or design the groove. Use
Materials , the
Chemical Compatibility Chart ,
Shore A Hardness , and
Groove Charts for those decisions.
Using this chart with the standard Match the measured or printed ID × CS (mm) to a row above. Note whether you need Class A precision (AS568-aligned) or a true metric CS group. Add compound and duro for the fluid and temperature. Order by store CS×ID code, or open the Master Chart when other standards are in play.
