O-Ring Standard
Cross Reference
Shortly after O-Rings first came into common use, it became obvious that standards for O-Ring sizes, tolerances, and groove design would be beneficial. The first standards were issued in 1942. Since then various
government and engineering organizations have produced a multitude of O-Ring standards.
From this large list we chose to include the following national and international O-Ring standards in the
cross reference tables presented in the following pages:
AS568
BS 1806
ISO 3601
DIN 3771
BS 4518
JIS B 2401
NF T47-501
SMS 1586
ISO 6149
All of these standards specify acceptable tolerance ranges, while some call out quality and/or material requirements. The O-Rings in this cross reference are presented without regard to any materials or
tolerances specified in the actual standards. We chose to list all sizes from each standard whether or
not PAI has current tooling. Short descriptions of each standard follow including any designation for tolerances, quality and material. A sample Part Number appears in brackets at the end of each description,
which are presented below in the order that they appear in our tables.
AS 568 is produced by the Society of Automotive Engineers AS (Aerospace Standard) 568 describes 379
O-Rings including tolerances for Cross Section (C/S) and Inside Diameter (ID). The five main cross section
groups are designed to be used in standard nominal inch applications. O-Rings are identified by - (dash)
numbers with the first number (0-5) of each group matching up to a nominal inch cross section. An additional group is designed for use as tube fitting boss seals. The dash numbers for these tube & boss
O-Rings begin with a 9. [ AS 568 - 123 ]
BS 1806 is issued by the British Standards Institution. This standard includes all of the 5 main cross section
groups in AS 568 plus extended sizes in the 1/4" nominal cross section group. Additional extended sizes
were included in earlier versions of this specification, but were later eliminated. We chose to include them
in this document since they are still in use. [ BS 1806 - 123 ]
ISO 3601-1 is authored by the International Organization for Standardization. This document contains two
groups of O-Rings. The first group, designated for General Industrial applications are "inch" sizes that for
the most part match up exactly to the AS 568 O-Ring sizes (the AS 568 tube fitting O-Rings are not
included). The ISO 3601-1 Size Code for these O-Rings is the same as the AS 568 dash number. The
second group of O-Rings are "metric" sizes and are designated for Aerospace applications. The first digit of
the Size Code indicates the cross section group (A-E), while the last four digits indicate the O-Ring inside
diameter rounded to one-tenth millimeter. Complete item designations for both types include the word
O-Ring followed by a hyphen and ISO 3601-1, followed by another hyphen and the Size Code and a letter
indicating the tolerance class, another hyphen and a description of the size, and a final hyphen and a letter
code indicating the Grade. Additionally, O-Rings intended for Aerospace use will be indicated by the letter
A following 3601-1 (3601-1A) in the item designation. The tolerance classes are designated by the letters A
and B (A is tighter). Aerospace O-Rings have only one tolerance class. Grade codes, N, S, and CS indicate General Purpose, Special, and Critical Service respectively. The grades are primarily visual inspection
standards and are defined in ISO 3601-3. [ O-ring - ISO 3601-1 - 011 A - 7,65 x 1,78 - S ] - General Industrial
[ O-ring - ISO 3601-1 A - C0545 - 54,5 x 3,55 - S ] - Aerospace
DIN 3771 is produced by the Duetsches Institut für Normung (German Institute for Standards). O-Ring
sizes are identified by the ID x C/S, followed by a letter indicating the Quality Level, and a code indicating
the rubber polymer and IRHD hardness. Two Quality levels are specified: N - Normal Quality (1.0 AQL),
S - Special Quality (.65 AQL). [ O-ring DIN 3771 - 13,2 x 1,8 - N - NBR 70 ]

O-Ring Standard
Cross Reference
NF T 47-501 is issued by the Association Française de Normalisation (French Standards Institute). It is
very similar to ISO 3601-1 in both the sizes included and part nomenclature. O-Rings are designated with a
size code that is made up of a letters corresponding to each of 5 cross section groups (A-E), 4 digits
indicating ID rounded to .1 mm, a 2nd letter indicating Precision Class and a 3rd letter indicating Visual
(inspection) Class. The Precision Class is indicated by the letter A, for Aerospace applications, and G for
General Purpose applications. The visual classes are N (1.0 AQL) and S (.65 AQL).
[ O-ring NF T 47-501 A0224 A S ]
JIS B 2401, a Japanese Industrial Standard, has two groupings of O-Ring sizes. The first group consists of
two sets of O-Rings designed for General Purpose and for Aerospace applications. These O-Rings are
mostly a subset of ISO 3601-1 with a few additional sizes. O-Rings are identified simply by their dimensions, ID first and then C/S, plus a Series Letter. The Series Letter is used to indicate the application:
G indicates General use, while A indicates Aerospace applications. Aerospace O-Rings are held to closer
tolerances than the General Purpose O-Rings. In our tables, the ISO O-Rings are indicated solely by the
letters A or G. [ O-ring 7.5 x 1.8 - G - S ]
The second, more traditional group is organized into three sections: Moving (dynamic), designated by the
letter P, Fixing (static), designated by the letter G, and Vacuum Flange, designated by the letter V. The
O-Rings in each section have insignificant ascending numbers to complete the size code. Like the ISO
group, the traditional part numbers include a Grade letter. In our tables the traditional group O-Rings are
identified by their size code labels. [ O-ring Type 1A G80 N ]
Unlike the other standards listed here, JIS B 2401 calls out 6 material classes: 1A, 1B, 2, 3, 4C and 4D. We
do not address them in this publication— see our Compound Selection Guide, or contact us for the PAI
compounds meeting these classes.
BS 4518, also from the British Standards Institution, identifies British Standard metric sizes. The size code
for these O-Rings is a four digit number indicating the O-Ring I.D. in tenths of millimeters followed by a hyphen and two digits indicating the O-Ring Cross Section, also in tenths of a millimeter. ] BS 4518 0645 - 24 ]
SMS 1586 is a Sveriges Mekanstandardisering (Swedish Mechanical Standard). O-Rings are simply identified by ID and C/S similar to DIN 3771. SMS 1586 O-Rings are classified into two groupings. The first
group, intended for dynamic and static installations is indicated in our table by the letter D. The second
group, intended mainly for static applications, is indicated with an S.
[ “O”-ring SMS 1586 3.3 x 2.4 - (mat’l per SMS 1587) ]
IS0 6149 covers O-Rings designed for use in Metric Tube Fittings. Unlike AS 568, ISO 3601 does not
include these O-Rings. There is a separate table on the last inside page of this publication that references
these 13 sizes.
The tables on the following pages list 1,484 different O-Ring sizes. While Precision Associates has over
2,200 O-Ring sizes, we are not tooled for all of the O-Rings in these pages. O-Rings that we are tooled for
are indicated in the first column of the table. If you find that we don’t have a tool listed, please call us as we
regularly ad sizes to our repertoire. If not, we can usually produce a mold in short order in our on-site mold
shop.
As stated earlier in this section, this publication is only intended to identify O-Ring sizes from the various
specification designations. Every effort was made to make sure that the information presented here is
correct, but we recommend referral to the actual specifications before proceeding with design work, etc.
You may contact Precision Associates for complete information regarding tolerances, inspection requirements and materials.
