Application Summary AI generated
GB/T 3452.4-2020 specifies the dimensions, materials, and performance requirements for anti-extrusion rings (back-up rings) used in fluid power systems. These rings are applied alongside O-rings in hydraulic and pneumatic cylinders to prevent seal extrusion under high pressure or dynamic conditions. The standard is primarily used by manufacturers and engineers in industries such as machinery, automotive, and aerospace for designing reliable sealing solutions in high-pressure fluid systems.
