When selecting hydraulic hoses, multiple factors need to be considered. Firstly, the pressure level is determined based on the working pressure of the hydraulic system to ensure that the pressure resistance of the selected hose meets the system requirements. Next is size and diameter. Based on the flow rate of the hydraulic system and the size of the connectors, select the appropriate inner and outer diameters of the hose to ensure that the inner diameter of the hose is large enough to meet the system requirements, and the outer diameter is suitable for the size of the connectors. The third is durability and wear resistance. Considering the durability and wear resistance of hydraulic hoses during use, the hoses should be able to withstand pressure pulsation, compression, bending and other operations in the system, and have good wear resistance to extend their service life. In addition, factors such as chemical resistance, temperature adaptability, bending radius, and compliance with relevant standards and certifications need to be considered.

In summary, when purchasing hydraulic hoses, selecting the appropriate hose can greatly improve the performance and lifespan of the hydraulic system, and can save customers cost budgets.
