What is the meaning of AS568?

AS568 is a specification for O-rings, a commonly used sealing device in various industries. It is a standardized system that sets dimensions, tolerances, and material requirements for O-rings. The AS568 standard is widely recognized and used in the United States, and it helps ensure compatibility and interchangeability of O-rings in different applications.

In the world of engineering and manufacturing, O-rings play a crucial role in sealing applications, preventing the leakage of fluids or gases. However, to ensure the proper functioning of these seals, it is necessary to have a standardized system in place for their design and dimensions. This is where the AS568 comes into the picture.

What is AS568?

AS568 is a specification published by the Society of Automotive Engineers (SAE), outlining a series of standard sizes for O-rings. The purpose of AS568 is to provide a consistent set of dimensions, tolerances, and material capabilities for O-rings. It enables manufacturers, distributors, and end-users to easily identify, source, and interchange O-rings that meet specific requirements.

Benefits of AS568.

By adhering to the AS568 standard, manufacturers and users of O-rings can enjoy several advantages. Let's explore them below:

1. Compatibility: AS568 ensures interoperability among different manufacturers' O-rings, allowing users to replace seals without compatibility issues. This greatly simplifies maintenance and spare parts management.

2. Availability: AS568-standard O-rings are readily available from numerous suppliers and distributors worldwide. With a wide range of options for each required size, finding the right O-ring for a particular application is much easier.

3. Quality Assurance: AS568 requires strict adherence to dimensional, material, and performance requirements. This enhances quality assurance and reduces the likelihood of seal failures, ensuring safe and reliable operation.

AS568 Size Designation.

The AS568 specification assigns a unique dash number to each size of O-ring, indicating its inside diameter, cross-section diameter, and tolerance range. The dash numbers range from -001 to -475 and cover an extensive inventory of more than 370 sizes. The inside diameter is specified in sixteenths of an inch, while the cross-section diameter is given in 1/16 inch increments.

The most common AS568 O-ring sizes fall within the range of -001 to -243, covering typical industrial applications. Specialized industries or niche applications may require O-rings beyond this range. By referring to the dash number, users can obtain O-rings with precise dimensions, ensuring a proper fit for their specific sealing needs.

Choosing the Right O-ring.

Selecting the correct O-ring size, material, and hardness is critical for optimal seal performance. The AS568 standard provides guidance for material selection based on the temperature range, chemical compatibility, and physical properties required for an application. By following these guidelines, engineers and manufacturers can make informed decisions when choosing O-rings suitable for their specific environments.

Conclusion.

In summary, AS568 is a standardized system that defines the dimensions, tolerances, and material requirements for O-rings. Its widespread acceptance and use in the United States simplify the sourcing and interchangeability of O-rings, enabling efficient seal design and maintenance processes. By adhering to the AS568 standards, manufacturers and users can take advantage of compatibility, availability, and quality assurance. So, whether you work in the automotive, aerospace, or any other industry that relies on O-rings, knowing about AS568 can greatly benefit you.
