This highly durable suction and discharge hose is engineered for low-pressure sections of hydraulic systems in compliance with SAE J517 100 R4, ensuring reliable performance in demanding industrial environments. Primarily designed for suction and oil return applications, it is compatible with mineral oil-based and selected synthetic hydraulic fluids, as well as water-based solutions up to +70°C. Its versatility extends to the transfer of various petrochemical liquids with low aromatic content, making it a flexible choice across multiple industries. The hose features a smooth, oil-resistant black synthetic rubber inner layer, reinforced with robust synthetic cord and a steel spiral that guarantees excellent vacuum resistance and outstanding flexibility without risk of kinking. The abrasion- and weather-resistant outer layer, also made of black synthetic rubber, provides long-lasting protection against external factors and light oil exposure. Available in standard lengths of 60 m (with 120 m options upon request), it offers working pressures from 2 bar to 21 bar depending on diameter, and a wide operating temperature range from -40°C to +100°C, making it a dependable solution for efficient and safe fluid transfer.
