1. Good flexibility and bending performance: hydraulic hoses are made of flexible materials and can be bent in different directions and angles, making them suitable for complex piping arrangements. They can move freely in tight spaces, thus providing greater flexibility in the design and installation of hydraulic systems.

2. High pressure resistance: Hydraulic hoses are usually composed of multiple layers of fabric, wire, or spiral-wound metal bands and other materials. These materials have excellent pressure resistance and can withstand the force of high-pressure fluids to ensure the reliable operation of hydraulic systems.

3. Good wear resistance and corrosion resistance: Hydraulic hoses are usually specially treated to have good wear resistance and corrosion resistance. They can withstand particles and chemicals in fluids, extending their service life and reducing maintenance costs.

4. Good sealing performance: Hydraulic hoses can be connected to other hydraulic components through appropriate connections (such as press-in fittings, twist fittings, etc.) to form a reliable seal. This helps prevent fluid leakage and ensures efficient system operation.

5. Quick installation and replacement: Compared with rigid hoses, the installation and replacement of hydraulic hoses are usually easier and faster. By using the appropriate connectors, the hose can be quickly connected and disconnected, saving maintenance and repair time.

6. Vibration absorption and shock absorption capacity: hydraulic hose has a certain degree of flexibility, and can absorb and reduce the vibration and shock loads in the system. This is important for the protection of other components in the hydraulic system (such as pumps, valves and machinery) and to improve the working stability of the system.

Overall, the hydraulic hose has the advantages of flexibility, pressure resistance, wear resistance, corrosion resistance, reliable sealing, etc., making it one of the common transmission components in the hydraulic system. However, when selecting and using hydraulic hoses, specific application needs and safety requirements still need to be considered to ensure the reliability and performance of the system.
