When choosing a hydraulic hose you should pay close attention to the following characteristics:

• Working Pressure - Choose a hose that is suitable for the working pressure of the machine
• Wire or Sheathing - Install wire or sheathing when fabricated if the hose will be used in an area exposed to damage from pinching or crushing
• Fluid - Make sure you use a hose compatible with the fluids that are used in the machine
• Size/Inner Diameter - Choosing the right size hose is important in order to avoid unwanted friction. When fluid rubs against the inner surface of the hose, friction is created, which creates heat, back pressure increases, and the rate of flow is reduced
• Match the Fluid Viscosity to the Operating Temperature - In order to achieve maximum component life, the fluid's viscosity grade should be correctly matched to the operating temperature range of the hydraulic system
