The core structure of the rubber suction and drainage hose consists of multiple layers of materials. The inner layer uses smooth synthetic rubber (such as EPDM, SBR or NBR) to ensure smooth water flow and reduce friction and energy loss. The middle layer is reinforced with high-strength textile fibers or synthetic fibers to enhance the hose's pressure resistance and anti-collapse performance, especially to maintain shape stability when vacuuming water.
