How do you read an O-ring size?
How to Measure O-Rings
- 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.

What do O-ring numbers mean?
Two dimensions describe the size of an O-ring: its inside diameter (ID) and its cross-sectional diameter (CS). The standard sizes used by major O-ring manufacturers are defined by Aerospace Standard AS568A, Aerospace Size Standard for O-rings.
What is the smallest O-ring size?
008 in. (. 20 mm) inside diameter and cross section – the smallest size o-ring in the world! MicrOring® seals were developed by Apple Rubber to meet the ever-increasing demand for effective seals in a wide range of miniaturized applications, from precision instruments and medical devices to aerospace and fiber optics.
What does CS mean in O rings?
Two dimensions describe the size of an O-ring: its inside diameter (ID) and its cross-sectional diameter (CS).

How can you tell the difference between EPDM and Viton?
Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges. Both have different properties and applications for general industrial use.
How tight should O rings be?
To provide an effective seal, the O-ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.
How are O rings shown in a catalog?
In most cases the O-Rings are presented from top-to-bottom and left-to right. In cases where O- Rings overlap, the label has been positioned so that it will identify only one size. O-Rings that are too large to illustrate are listed in cross sectional groups at that back of the catalog
How to tell the size of an O ring?
O-Rings are identified by ID and C/S. The German Institute for Standards (Duetsches Institut für Normung). O-Ring sizes shown as ID x C/S. Association Française de Normalisation (French Standards Institute). Similar to ISO 3601-1. Japanese Industrial Standard for o-ring sizes.
Which is the Japanese standard for O rings?
Japanese Industrial Standard for o-ring sizes. This standard, often referred to as “Japanese Metrics.” ISO 6149 specifies o-rings designed for use in Metric Tube Fittings. Includes 13 different sizes and calls out the metric thread size for each o-ring size.
Are there Class A and B O rings?
International Organization for Standardization and contains both Class A and Class B O-Rings. Issued by the British Standards Institution, Standard BS 4518 identifies British Standard metric sizes. Swedish Mechanical Standard (Sveriges Mekanstandardisering).
