The AS568 Parker standard sets the benchmark for O-ring sizes and specifications across various industries, making it an essential reference for engineers, designers, and manufacturers. Founded by Parker Hannifin, a globally recognized leader in motion and control technologies, the AS568 standard has transformed how O-rings are produced, measured, and implemented in systems worldwide.
Understanding AS568 Parker Standards
The AS568 standard provides a comprehensive catalog of O-ring sizes, detailing their dimensions, tolerances, and sometimes materials. It is crucial for professionals in industries such as aerospace, automotive, oil and gas, and medical devices, where equipment reliability and performance are non-negotiable. The standard ensures that the right O-ring is used for the right application, minimizing the risk of equipment failure.
Key Features of AS568 Parker Specifications
At the heart of the AS568 standard are the specific dimensions it outlines—inner diameter (ID), outer diameter (OD), and cross-section thickness of O-rings. Each size is assigned a unique identification number, facilitating easier communication between suppliers and manufacturers. The standard covers over 370 sizes, ranging from standard to non-standard options, accommodating various design requirements.
O-Ring Materials Under AS568
While the AS568 standard defines dimensions, the material selection is left to the discretion of the designer, depending on the application conditions. Common materials compliant with AS568 include nitrile, fluorocarbon, silicone, and EPDM, each offering different chemical resistance, temperature ranges, and flexibility. Understanding the operational environment is critical for selecting the appropriate material, which can significantly affect the performance and longevity of the O-ring.
Applications of AS568 Parker O-Rings
O-rings specified under AS568 are utilized in an array of applications—sealing hydraulic cylinders, preventing leaks in piping systems, and ensuring airtight seals in aerospace components. Their versatility and reliability make them a staple in machinery and equipment used across various sectors. The high standards of AS568 Parker ensure that O-rings can withstand extreme pressures and temperatures, reinforcing their importance in engineering projects.
Buying AS568 O-Rings
When purchasing AS568 O-rings, it is vital to ensure that suppliers provide certified materials adhering to the standards. Quality assurance not only includes checking dimensions but also testing the material's properties to ensure compatibility with specific applications. Numerous manufacturers offer AS568-compliant O-rings, but it is advisable to choose well-reviewed suppliers with a track record of quality and reliability.
Conclusion: A Valuable Resource
In summary, the AS568 Parker standard is not just a collection of size specifications; it represents a commitment to quality and reliability in fluid sealing. For anyone involved in product design or manufacturing, understanding AS568 ensures that the right components are chosen to enhance performance and dependability in their systems. By standardizing O-ring dimensions, Parker offers a vital resource that streamlines production and enhances operational efficiency.
