Universal Standard O-ring Size Chart

Universal Standard O-ring Size Chart

AS-568 Standard O-ring Size Chart is an American National Standards Institute (ANSI) standard for O-Ring sizes developed by the Rubber Manufacturers Association (now the Rubber Industry Association). The AS-568 standard defines a series of standardized O-Ring sizes for a variety of industrial and commercial applications, particularly in aerospace, automotive, hydraulic and pneumatic systems.

Key features and elements of the AS-568 standard include:

Range of sizes: The AS-568 standard covers a range of O-ring sizes from small to large, including inside diameter (ID) and cross-sectional diameter (CS). These sizes are suitable for different pressure and temperature conditions.

Numbering System: Each O-ring in the AS-568 standard has a specific three-digit number that corresponds to its size. For example, the number 340 usually indicates a specific combination of inside and cross-section diameters.

Material Type: Although the AS-568 standard focuses primarily on the size of the O-ring, it usually mentions the type of material that is applicable, such as Nitrile Rubber (NBR), Fluorocarbon Rubber (FKM), Silicone Rubber (VMQ), etc., to suit different operating environments and media.

Tolerances: The AS-568 standard specifies tolerance ranges for O-ring dimensions to ensure that O-rings are manufactured to meet specific sealing requirements.

Application Guidelines: The AS-568 standard may also include recommendations on the installation and use of O-Rings and how to select the proper O-Ring to meet the needs of a particular application.

Quality Control: Manufacturers of AS-568 compliant O-Rings typically follow strict quality control procedures to ensure that each O-Ring meets the dimensional and performance requirements specified in the standard

O-Ring Size Measurement:

1. Inside Diameter (ID) Measurement:

Use calipers or an ID micrometer to measure the inside diameter of the O-ring.

Measurements should be made to ensure that the O-ring is not twisted or deformed.

Usually measure two or three different locations to ensure consistent dimensions.

Record the smallest measurement as this is usually the tightest dimension of the O-Ring during assembly.

2. Cross-section diameter (CS) measurement:

Use an OD micrometer or micrometer gauge to measure the cross-section diameter of the O-ring.

Take measurements at several different locations on the O-ring, usually at four equal points along the circumference.

Record the largest measurement, as this is usually the loosest dimension of the O-ring during assembly.

3. Cross-sectional shape check:

Use a projector or microscope to check the cross-sectional shape of the O-ring.

Ensure that the cross-section is round with no ovality or other distortion.

If irregularities are found in the cross-sectional shape, further inspection of the manufacturing process or material quality may be required.

4. Hardness test:

Use a hardness tester to measure the hardness of the O-ring, which is important for determining material properties and suitability.

Hardness tests are usually performed at several different locations on the O-Ring to ensure consistency.

5. Tolerance checking:

Check the dimensional tolerances of the O-Ring according to the relevant standards (e.g. AS568).

Ensure that all measurements are within the specified tolerances.

6. Material and color check:

Check the material type and color of O-rings to ensure they meet requirements.

This is usually done through visual inspection and material identification testing
