Use our o-ring size chart and calculator to find the AS568 or metric sizing of standard size HNBR, Viton, and other o-rings.

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.

O-ring size charts for U.S. and metric o-ring sizes. Find the right size o-rings, quad-rings, x-rings and square-rings for your application. Custom and non-standard o-ring sizes available with no tooling or setup fees.

ISO 3601-1 specifies the inside diameters, cross-sections, tolerances, and designation codes for imperial and metric o-rings used in fluid power systems for general industrial and aerospace applications.

The standard sizes used by O-ring manufacturers in the United States are defined by Aerospace Standard AS568B, Aerospace Size Standard for O-rings. That document, published by the Society of Automotive Engineers (SAE), lists the sizes of O-rings in six series or groups in both inches and millimeters.

All metric O-Ring dimensions are defined by their CS (Cross Section) and ID (Inside Diameter). For example, an O-Ring labeled N2.00X012 has a 2 mm cross section and a 12 mm inside diameter, making it easy to understand and select the exact size needed.

2021年5月7日 · o形圈的尺寸参数以内径、外径、线径来标识的。通常外径是以od表示，内径是以id表示，线径是以cs表示。 o形圈型号表示方法主要分为两种形式，一种为外径线径(odcs)，一种为内径线径(idcs)， 目前g内外用的广泛的就是内径线径的表示方法。

An O-ring is a solid-rubber seal shaped like a doughnut or torus. When compressed between mating surfaces, an O-ring blocks the passage of liquids or gases. Parco O-rings are available in a wide range of standard and non-standard sizes that are suitable for nearly all sealing applications. Two dimensions describe the size of an O-ring: its

Standard o-rings are available in various cross-sections and inside dimensions (ID). For example, an o-ring with an ID of 5 ¼ can be purchased in four standard AS568 cross-sections. Below, is a list of advantages in the selection of smaller and larger cross-section o-rings.

Custom large O-Rings 5” and larger inside diameter can be vulcanized. 1847 Wilma Dr, Clarkston, WA 99403 | Phone (208) 413-6377 Fax (208) 413-6719 *001 Cross-section measures 1/32” *002 Cross-section measures 3/64” ID
