O-Ring Size Chart
The Master O-Ring Size Chart
This page is the AS568 dash chart. Use it when you already have a dash number, such as AS568-214, and you want the nominal and exact ID, OD, and cross-section. The Master O-Ring Size Chart is the chart on the O-Ring Handbook for a measured size or for a print that names another standard. Search by inside diameter or cross-section and it checks AS568, ISO 3601, JIS B 2401, DIN 3771, BS 1806, BS 4518, and the other standards together, with the closest sizes first. The O-Ring Store publishes the handbook at oringhandbook.com.
O-rings are actually really easy to measure. All you need to do is measure the internal diameter (ID) or outside diameter (OD) and the width or cross section (C/S) of the o ring. The diagram shows exactly where these dimensions are to be found. Once you have these measurements you then need to decide if the size you need is listed below or if the best fit will be a metric oring. Once you have the AS-568 dash size you need, select the compound link at the bottom of the page to place your order.
Calipers, pi-tape, size cones, slide gauges, and Olypsys® are covered on the O-Ring Handbook.
To calculate an o-ring's outside diameter (OD) you may use this formula: 2(CS) + ID = OD
If you have the OD and need to find the ID use this formula: OD - 2(CS) = ID

O-Ring Handbook size charts
Each standard has its own chart on the O-Ring Handbook. Scroll inside the list to see every one, then open the chart that matches the print.
| Chart | What this chart covers |
|---|---|
| AS568 | Inch dash numbers in SAE AS568, from the 0xx series through the 4xx series. The table on this page is that list. The handbook page explains how a dash number is built and what each series means. |
| Metric / ISO 3601 | Metric O-Rings named by inside diameter and cross-section in millimeters. ISO 3601 is the series used on most international and European prints. |
| JIS B 2401 | Japanese standard sizes in the S, P, G, and V series, with inside diameter and cross-section in millimeters. |
| ORB Boss | AS568 900-series boss seals for SAE J1926 tube-fitting ports. The chart lists the dash, the tube size, and the thread. |
| Backup Rings | AS568 back-up rings that sit beside an O-Ring under high pressure. Dimensions cover inside diameter, width, height, and contour. |
| DIN 3771 | German and European metric sizes under DIN 3771, listed as inside diameter and cross-section in millimeters. |
| Generic Metric | Common metric tooling sizes, inside diameter by cross-section in millimeters, including sizes molded outside a single national table. |
| BS 4518 | British metric O-Ring sizes. Inside diameter and cross-section are in millimeters. |
| BS 1806 | British imperial dash numbers. The series lines up with AS568, which helps when a UK print calls the size out as BS 1806. |
| NF T 47-501 | French metric sizes under NF T 47-501, with inside diameter and cross-section in millimeters. |
| SMS 1586 | Swedish and Nordic metric sizes under SMS 1586, with inside diameter and cross-section in millimeters. |
| X-Ring | Four-lobed seals on the same AS568 dash numbers as a round O-Ring. Quad-Ring® is the trade name most drawings use for this profile. |
| Square Ring | Square-profile seals on AS568 dash numbers. The wall is a little thinner than the round O-Ring of the same dash, so the ring can sit in a standard gland. |
| Parker 500 | Parker 5-xxx catalog sizes, with inside diameter, cross-section, and outside diameter in inches and millimeters. |
| ISO 6149 | Seals for ISO 6149 metric ports and fittings, listed by port thread and a cross-section by ID code. SAE J1926 inch boss seals are on the ORB Boss chart. |
