The hydraulic oil and the rubber layer inside the hose must be compatible, and the compatibility of rubber is usually evaluated by the index of volume change and hardness change.

As phosphate ester-based and petroleum-based hydraulic fluid chemical properties are very different many hoses are suitable for one or more hydraulic fluids, but not for all Many hoses are suitable for one or more hydraulic fluids, but not for all types of hydraulic fluids.

Poor compatibility between the hydraulic fluid and the inner layer of the hose is the cause of premature The reason for the premature aging of the inner layer of the hose is the direct cause of oil leakage, because the hydraulic oil and the inner layer of the hose In the process of contact with the inner rubber layer, the low molecules in the hydraulic oil will gradually penetrate into the rubber’s The hydraulic oil will gradually infiltrate into the mesh structure of the rubber, and at the same time, the resistance of the rubber mesh molecules will finally reach the balance, triggering the volume, hardness and tensile properties of the rubber to The change in volume, hardness and tensile properties of the rubber is triggered.

High quality hydraulic oil is the guarantee of reliable operation of hydraulic system. Different brands of hydraulic oil should not be mixed to prevent the hydraulic oil from chemical The hydraulic oil of different brands should not be mixed to prevent the hydraulic oil from chemically corroding the inner rubber layer of the hose and causing the inner rubber layer to crack.

Xuyuan Hydraulics’ technology is sufficient to support us in finding this balance.
