Product Description
Hydraulic Oil Hose For Return System
Product Introduction:
Our Hydraulic Oil Return Hose is specifically designed for low-to-medium pressure applications in hydraulic systems, with a primary focus on return lines and suction lines. It safely conveys hydraulic oil back from actuators, control valves, and motors to the reservoir or tank. This hose is widely used in industrial machinery, construction vehicles, agricultural equipment, and mobile hydraulic systems.
Unlike high-pressure hoses used in pump discharge lines, our return hose is optimized for low working pressures, high oil flow volume, and resistance to oil aging and heat buildup, ensuring reliable and long-lasting performance in non-pulsating or mildly pulsating return circuits.

Key Features:
1.Designed for Return & Suction Lines
Engineered to handle the low-pressure side of hydraulic systems (typically working pressure up to 10–30 bar / 150–450 psi), making it ideal for oil return paths from cylinders, motors, and valves back to the tank.
2.Excellent Oil Compatibility
The synthetic rubber inner tube resists degradation caused by mineral hydraulic oils, biodegradable hydraulic fluids, and lubricating oils commonly used in machinery and vehicle systems.
3.Crush & Kink Resistance
Built with spiral fabric reinforcement or light steel wire helix (depending on grade), the hose maintains its round cross-section under vacuum or bending, preventing collapse in suction applications.
4.Smooth Inner Bore
A smooth inner surface minimizes flow resistance and turbulence, allowing hydraulic oil to return freely to the tank without pressure buildup or cavitation risks.
5.Weather & Abrasion Resistant Cover
The outer rubber layer withstands exposure to sunlight, moisture, dirt, ozone, and mechanical abrasion – ideal for outdoor machinery, construction sites, and agricultural environments.
6.Wide Temperature Range
Operates reliably from -20°C to +80°C, accommodating both cold-start conditions and continuous hot oil return cycles.
