What Are High-Pressure and Low-Pressure Hydraulic Hoses?
Hydraulic hoses are used to transfer oil, air, or other fluids in industrial and automotive systems. The main difference between high-pressure and low-pressure hydraulic hoses lies in their material, pressure tolerance, and application.
Structure of High-Pressure vs Low-Pressure Hydraulic Hoses
High-Pressure Hydraulic Hose:
-
Constructed with multiple layers reinforced with steel wires.
-
Typically designed for pressures above 300 bar.
-
Suitable for high-pressure automotive and industrial applications.
Low-Pressure Hydraulic Hose:
-
Typically made of rubber layers or cotton-braided fabric.
-
Designed for pressures below 50 bar.
Applications of High-Pressure and Low-Pressure Hydraulic Hoses
Use in Heavy-Duty Vehicles:
-
Trucks require high-pressure hoses for air brake systems, hydraulic steering, and jacks.
Use in Industry:
-
Forklifts, excavators, CNC machines, and cranes utilize high-pressure hoses.
-
Low-pressure hydraulic hoses are used for cooling, lubrication, and fuel supply systems.
How to Choose Between High- and Low-Pressure Hydraulic Hoses
-
Check system pressure: If operating pressure exceeds 100 bar, use a high-pressure hose.
-
Working temperature: For high-temperature environments, choose heat-resistant hoses.
-
Material and brand: Brands certified by DIN and SAE standards offer higher quality.

Frequently Asked Questions About Hydraulic Hoses
What is the main difference between these two types of hoses?
High-pressure hoses have reinforced steel layers, while low-pressure ones are made of rubber or fabric braiding.
Can a low-pressure hose be used in high-pressure systems?
No. This is dangerous and may cause hose rupture and serious system damage.
Conclusion
Understanding the difference between high- and low-pressure hydraulic hoses helps you make safer, more accurate, and more efficient choices. When in doubt, consulting a technical expert is always recommended.
