How do you read an O-ring size?

How to Measure O-Rings

  1. Place the O-ring on a clean, flat, level surface.
  2. Determine the inside diameter by using a ruler to measure from one inner edge to another.
  3. Use a ruler to measure the diameter, from one outer corner of the O-ring to the other outer corner.
  4. 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?

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?
