The inner rubber layer of the Compound-TN01 hydraulic oil-resistant hose is a key component of the hose. It has excellent oil resistance and stability, and can maintain the characteristics of not easy to age and crack in harsh working environments. The high strength and elasticity enable it to withstand the pressure changes and mechanical stress in the hydraulic system, and it is not easy to crack or deform. At the same time, it has low air permeability, which can prevent oil leakage and external gas from entering, ensuring the pressure stability and working efficiency of the hydraulic system. The inner rubber layer of the hydraulic oil-resistant hose has excellent performance in oil resistance, heat resistance, aging resistance, etc., providing an important guarantee for the normal operation of the hydraulic system.
