PU Tube, short for polyurethane hose, combines excellent flexibility, strong resilience, wear resistance, low-pressure endurance, lightweight property, easy cutting and installation, reliable sealing and moderate corrosion resistance. Compared with PVC, rubber and PE hoses, it has wider adaptability and longer service life, making it a mainstream flexible conveying tube for industrial and civil fields. It is widely used in fluid transportation and pneumatic power transmission scenarios and covers nine major industries with clear practical application cases.
The industrial automation and mechanical equipment industry represents the most important application field of PU Tube. Various automated production lines, robotic arms, pneumatic solenoid valves and cylinder devices all adopt PU Tube as standard pipeline for compressed air delivery to supply power for pneumatic components. Its rapid rebound and bending fatigue resistance adapt to frequent motion and repeated bending of equipment. It resists deformation and blockage, features simple installation and neat wiring, and is widely deployed in electronic automation, hardware processing, intelligent manufacturing and other industrial machinery as core consumables for pneumatic systems.
PU Tube sees extensive application in automobile manufacturing and auto parts. With oil resistance, mild corrosion resistance and great flexibility, it fits the narrow and complex installation space inside vehicles. It is mainly used for automobile pneumatic brake systems, seat adjustment pneumatic pipelines, pneumatic lamp assemblies and door shock absorption pneumatic lines. It also serves auxiliary delivery of clean water spray and low-pressure oil circuits. The tube resists vibration and deformation and copes with bumps and shaking during vehicle travel without easy cracking or air leakage, maintaining high stability.
Food-grade and medical-grade modified PU Tube is preferred in medical devices and health care equipment. Medical PU Tube is non-toxic, odorless, hygienic, corrosion-resistant and easy to disinfect, complying with medical and health standards. It is applied in ventilator pipelines, negative pressure suction equipment, medical pneumatic instruments and fluid delivery for rehabilitation devices. It is also used for air delivery pipes in home oxygen concentrators and nebulizers. The material is safe with no substance precipitation, fitting human contact and clean medical scenarios.
Packaging, printing and textile industries adopt PU Tube on a large scale. Packaging machines, printing machines and textile machinery rely on PU Tube in their pneumatic control and tension adjustment systems to transport compressed air. Pipelines must bend and move repeatedly following mechanical actions during machine operation. The high rebound and anti-fatigue performance of PU Tube perfectly satisfies such requirements and effectively prevents pipeline deformation, damage and air leakage, ensuring continuous stable equipment operation and reducing failure rates.
Application of PU Tube keeps expanding in smart home and light consumer industries. Household water purification equipment, fresh air systems, smart bathroom products, robot vacuum cleaners and pneumatic doors and windows commonly use small-size PU Tube for air and water conveyance. It is lightweight, aesthetic and simple to install, odor-free and mildew-resistant, fitting enclosed indoor environments. It is also applied in pneumatic toy assemblies and small household appliance fluid pipelines and other light industrial goods.
In addition, PU Tube is widely used in aquaculture, light chemical industry, hardware bathroom and garden irrigation. In aquaculture, it works as air delivery tubes for aerators for its resistance to corrosion and water vapor erosion. In light chemical sectors, it conveys clean water and weakly corrosive fluids under low pressure. For garden and bathroom applications, it handles small-scale water and air transmission. With comprehensive performance advantages, PU Tube acts as a general-purpose flexible tube covering most low-pressure fluid and pneumatic transmission scenarios.
