14. O-ring Size Charts Note: The AS O-ring Size Chart has a column that shows the Nominal Size along-side the Actual Size. Originally the nominal size was just for a listing of the approximate fractional dimensions of the O-ring. Prior to the common use of dial calipers many people called out a 1 inch by 1-1/4 rt = O-ring, this was a dash -214

Size Chart. [PDF] Available O-Ring Tooling Sizes. AS568 is the Aerospace Size Standard for O-rings from the Society of Automotive Engineers. SAE Aerospace Standard (AS) specifies the inside diameters, cross-sections, tolerances, and size identification codes (dash numbers) for O-rings used in sealing applications and for straight thread tube

O-rings manufactured from compounds with different shrinkage rates will provide slightly different dimensions and tolerances when standard tooling is used.

O-Rings. O-rings are circular sealing elements with circular cross-sections. They are mainly used in static applications. The sizes are determined by the inside diameter and the cross-section diameter. Parker O-Rings are manufactured according to international metric and imperial standards such as AS 568B, DIN ISO 3601 and JIS.

The tables in the O-ring Size Chart list approximately 2000 O-ring sizes in order by inside diameter. These O-ring sizes correspond to US Standard AS568, British Standard, Swedish, as well as many common metric sizes according to. DIN and ISO standards. Most of these sizes are readily available from.

O-rings are circular sealing elements with circular cross-sections, and are mainly used in static applications. The sizes are specified by the inside diameter and the cross section diameter. Our O-rings are manufactured according to metric and imperial international standards such as AS 568B, DIN ISO 3601 and JIS. Custom sizes of almost any dimension are possible, such as miniature O-rings

Some of the standards referenced here specify the acceptable tolerance ranges for the o-rings within that standard. However, With the exception of our AS568 Size Chart, our other size reference charts do not list tolerances, as these tend to vary between the standards issuing organizations.
