Specifications:
The document provides detailed specifications for hydraulic hoses, specifically the 2 SN type. Key parameters include internal and external diameters, reinforcement diameter, working and burst pressures, minimum bending radius, and weight per meter. The hoses are made with oil-resistant synthetic rubber tubes, reinforced with two high tensile steel wire nettings, and covered with synthetic rubber that is resistant to abrasion, ozone, and weather conditions. The temperature range for these hoses is from -40°C to +100°C. They comply with DIN EN 853 and SAE 100 R2S standards.
