O-rings

AS568 O-ring size chart

AS568 lists 369 standard O-ring sizes: 349 general-purpose sizes, 346 of them in five cross sections from 0.070 in to 0.275 in plus -001 to -003 below that, and 20 boss seals from -901 to -932. This chart carries every size with inside diameter, cross section and tolerances in inches and millimeters, and each dash number links to its own page with STEP and DXF files and a dimensioned PDF drawing. The dimensions are the AS568 (SAE Aerospace Standard) sizes, the same figures every size page carries. ISO 3601-1 writes a metric size with its own code, such as C0250 for 25.0 x 3.55 mm; its list is on the ISO 3601-1 metric size page, each size beside the nearest AS568 size, not an equivalent; the print governs. Send the dash number, the compound and the quantity and we quote it.

How the AS568 dash number maps to metric sizes

The AS568 dash number is a catalog lookup, not a formula. The first digit names the cross-section series, 0xx at 0.070 in through 4xx at 0.275 in, and the rest of the number is the position in that series, so -214 and -216 share a cross section but not an inside diameter. Three sizes, -001 to -003, sit below the 0.070 in cord and have no metric counterpart. The 900 series is separate: 20 straight-thread tube boss gaskets from -901 to -932 that ISO 3601-1 does not carry.

ISO 3601-1 groups its metric cross sections A to E, and each group's cord sits next to one AS568 series cord: 1.8 mm against 1.78 mm, 2.65 mm against 2.62 mm, 3.55 mm against 3.53 mm, 5.3 mm against 5.33 mm and 7.0 mm against 6.99 mm; we supply metric O-rings to ISO 3601 in nitrile, FKM, EPDM, silicone, HNBR and FFKM. ISO 3601-1 writes each metric size with its own code, a group letter and the inside diameter in tenths of a millimeter, so C0250 is 25.0 x 3.55 mm. JIS B 2401 is a different system: its number is a catalog index, never the inside diameter, and only its 3.5 mm cord overlaps an AS568 section cleanly.

Tolerances grow with the size. Dash -001 carries an inside-diameter tolerance of plus or minus 0.004 in and a cross-section tolerance of plus or minus 0.003 in; the 4xx series carries plus or minus 0.033 in on inside diameter and plus or minus 0.006 in on cross section. Every size page on this site lists both tolerances in inches and millimeters next to the STEP and DXF files and the PDF drawing.

To order, send the dash number, the compound and the quantity. If the print carries a metric size or a JIS number, send that instead and we quote the ring as drawn. The ISO 3601-1 metric size page names the nearest AS568 size for each metric size, not an equivalent; the print governs.

AS568 to metric

The six cross-section series, and the nearest ISO 3601-1 size

The first digit of a dash number names its cross-section series, and each of the five general-purpose series has its cord next to one ISO 3601-1 group's cord. The inside diameter is the open question: ISO 3601-1 lists metric diameters, so the tables below give the nearest ISO 3601-1 size and the difference in inside diameter, in millimeters and as a percentage, as a plain reading. The print governs; any change of size or standard is the buyer's engineering decision.

A negative difference means the nearest metric ring's inside diameter is smaller than the AS568 size; a positive one, larger. The print governs; whether a different size or standard can be used is the buyer's engineering decision, not a reading from this table. The full ISO 3601-1 metric list, every code in groups A to E with the nearest AS568 size (not an equivalent; the print governs), is on the ISO 3601-1 metric size list; every AS568 size converted to millimeters is on the AS568 chart in millimeters, and the metric sizes guide explains the ISO 3601-1 code.

Frequently asked

How many sizes does AS568 define?

The current revision, AS568F, lists 369 sizes: 349 general-purpose rings in the 0xx to 4xx series plus 20 boss gaskets in the 9xx series for straight-thread tube ports. The 9xx rings have their own sections, for example -901 at 0.185 in inside diameter and 0.056 in cross section. This site carries a page for every one of them.

What do the nominal fractions next to a dash number mean?

They are the nominal inside diameter and cross section in inch fractions, and they are not the ordering dimensions. A -214 is nominally 1 in by 1/8 in but measures 0.984 in inside diameter and 0.139 in cross section, and a -425 is nominally 4-1/2 in by 1/4 in against an actual 4.475 in by 0.275 in. Order by the dash number or by the actual dimensions in inches or millimeters.

How deep and wide should the groove be for a given cross section?

The gland depends on the seal type, not just the section: the same 2xx ring takes a different depth and width in a static face seal than in a reciprocating rod or piston seal. Where the print calls out AS4716, AS5857 or ISO 3601-2, that standard governs; otherwise send the seal type with the ring size and the quote works from the ring maker's gland tables.

My drawing says 2-214. Is that the same as AS568-214?

Yes. The 2-xxx prefix is a manufacturer's numbering that carries the AS568 dash number, so 2-214 is the AS568-214 ring.

Can you supply a size that is not on the AS568 chart?

Yes. Non-standard sizes come three ways: an ISO 3601 metric size, a size from another standard that the print names, or a ring molded to your inside diameter and cross section. Molded specials come from the molders we source from; send the two dimensions, the compound and the quantity and we quote the closest standard size alongside the exact one.
