In industrial applications, air ducts and flexible hoses are often used interchangeably, but they are fundamentally different. Rigid ducts are suitable for stationary high-pressure systems, while flexible hoses are designed specifically for mobile applications. Choosing the right type is crucial for safety, efficiency, and equipment lifespan.

Polyurethane hoses have the advantages of durability, flexibility and corrosion resistance. They are widely used in industrial, automotive, agricultural and medical fields, promoting industry innovation and development with high efficiency.
