GB/T 3452.1-2005 standard specifies the size series and tolerances of O-rings for rubber sealing for hydraulic pneumatic applications. O-rings play a key sealing role in hydraulic pneumatic systems, ensuring the normal and reliable operation of systems and components. This standard is divided into general purpose (G series) and aviation and similar applications (A series), covering the specific provisions of inner diameter, cross-sectional diameter and their tolerances. For different application needs, appropriate processing methods are provided to ensure the suitability of various synthetic rubber materials. The standard also describes in detail the shape, structure and method of determining the size identification code of O-rings, so that users can correctly select and apply O-rings to meet engineering design and use requirements. The formulation of GB/T 3452.1-2005 is designed to follow the principle of international standards and provide a unified technical standard basis for the hydraulic and pneumatic field.
