SAE 100 R4 hydraulic hose is suitable for delivering petroleum-based hydraulic oil. It is composed of three parts: tube, reinforcement and cover. Tube is made from oil resistant synthetic rubber, making hose have excellent performance in delivering petroleum-based hydraulic oil. Reinforcement is made from one layer or multiple layers of cloth or textile fibers with proper steel wire spiral, making hose suitable for high working pressure environment. Cover is made from oil and weather resistant synthetic rubber, making hose suitable for terrible working environment.
