Place the O-ring on a clean, flat, level surface. Determine the inside diameter by using a ruler to measure from one inner edge to another. Use a ruler to measure the diameter, from one outer corner of the O-ring to the other outer corner. Finally, measure the cross-section. Place the O-ring into a vernier caliper. Lightly clamp the jaws of the ...

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.

Cross-section. Select an O-Ring cross-section size from the available standard sizes. If you are unsure what cross-section size to use, see here. Clearance. Determine the maximum clearance present in your application. For a radial seal, subtract the minimum …

To get the dimensions of an AS-568A o-ring in millimeters, enter the 3-digit dash number and then press submit to get your "Fast DashTM" answer. Dash No. To get a dash number based on dimensions select the cross-section and enter either the actual ID, or the actual OD in millimeters. Then press submit to get your "Fast DashTM" answer.

This O-ring is made of black Buna-nitrile, is round in cross-section, has a durometer of 70A, and is designed for use in a wide variety of sealing applications. Buna-nitrile can have high tensile strength, and abrasion, tear, and compression set resistance.

For more information on O-ring sizes click to see the JIS B 2401 Standard O-Ring Size Tables. Dimensionally specifying an o-ring can typically be done with just two dimensions, the inner diameter (ID) and the cross-section (CS). Occasionally, an …

The three digit size number -225 is from the AS568 chart and will tell you the exact cross section and ID of the O-Ring. In this example the AS568 size is -225, which belongs to the 2 series group of O-rings, meaning the O-ring has an actual cross section of 0.139.

Welcome to our AS568 O-ring Size Chart section. This O-ring size chart provides a list of standard AS568 O-ring sizes. Most industries consider AS568 specifications, standard O-ring sizes. Each AS568 dash number is a unique number that denotes specific O-ring dimensions.

groove or gland will also vary with the cross section of the ring, the type of operation, and the amount of pressure used in the system. These dimensions will also be different if the O-ring is sealing a liquid which has a low volume swell on the ring (0-15% Design Chart 1&3) or if it is sealing a liquid which

if the ID of the O-ring is stretched, the cross-section of the O-ring will decrease. The following tables give the O-ring cross-sections that result from ID stretch. The new cross-section should be used for all compression and gland fill calculations for piston-type and external pressure face seals.

An O-ring seal is used to prevent the loss of a fl uid or gas. The seal assembly consists of an elastomer O-ring and a gland. An O-ring is a circular cross-section ring molded from rubber (Figure 1-1). The gland — usually cut into metal or another rigid material — contains and supports the O-ring (Figures 1-2 and 1-3). The combination of ...

The seal cross‐sectional tolerance was taken from standard O‐ring designs. The important thing to note is the variance created by the tolerance. The 2" design will end up with about 8.5 percent variance in the squeeze (12.59 – 4.07 = 8.52), while the 10" design has 10.7 percent variance.
