A 6mm PU (polyurethane) hose is a flexible, durable, and lightweight tube used for transporting fluids and gases, including air, water, and some chemicals, across various industries like automation, agriculture, and medicine. Key applications include pneumatic systems, fluid transfer lines, garden irrigation, and as instrument or fuel delivery lines. The hose's properties of high elasticity, excellent oil and wear resistance, and good aging resistance make it a reliable choice for many general-purpose and industrial uses where flexibility is crucial.
