They are widely used in various industries, including pneumatics, automation, and medical applications, due to their durability, flexibility, and resistance to abrasion, oils, and chemicals. PU tubes offer advantages over other materials like PVC and nylon in certain applications, particularly where high pressure, tight bends, and frequent movement are involved
