HG/T 2579-2008 (English Version) PDF

Scope: This standard specifies the classification, requirements, test methods, inspection rules and labeling, packaging and storage of O-shaped rubber sealing ring materials used in ordinary hydraulic systems that are resistant to petroleum-based hydraulic oil and lubricating oil (grease). This standard is applicable to O-shaped rubber sealing ring materials that are resistant to petroleum-based hydraulic oil and lubricating oil (grease) in ordinary hydraulic systems and have operating temperature ranges of -40°C to +100°C and -25°C to +125°C respectively.
