A flexible rubber hose used for conveying liquids, viscous fluids, and powdered solid materials, the braided rubber hose consists of an inner rubber layer, multiple layers of braided fabric or yarn wrapped layers, and an outer rubber layer; some models are reinforced with spiral steel wire. Its structure is divided into inner rubber layer + middle skeleton reinforcement layer + outer rubber layer, with the braided layer in the form of weaving, wrapping, and spiral steel wire layers. It features small outer diameter tolerance, oil resistance, heat resistance, and wear resistance, with a minimum bursting pressure four times the working pressure.
