PU Tube For Pneumatic Systems

Our company was founded in 2007 and has been committed to the research and development, production, and sales of polyurethane products since its establishment. The main products produced are polyurethane air tubes, polyurethane wheels, polyurethane boards, polyurethane mesh screens, and polyurethane coke cleaning balls. Our company has a strong technical team, production team, and sales team. We have 7 advanced extrusion production equipment and testing equipment. The PU tubes for pneumatic systems produced have received unanimous praise from customers for their high-quality products.

PU tube for pneumatic systems serves as the "blood vessel" for transmitting compressed air in pneumatic systems. However, it is widely chosen because it simultaneously acts as a "wear-resistant joint" and a "pressure-resistant armor." In short, it is not just a conduit-it is a critical safeguard that ensures the system operates efficiently and reliably.

Specifically, its role is reflected in the following aspects:

1. Efficient, Low-Resistance Compressed Air Delivery

This is the most basic function of PU tubing: to stably transport compressed air from the air compressor to actuators such as cylinders, valves, and pneumatic tools. To fulfill this purpose, PU tubing is designed with the following optimizations:

Smooth inner walls minimize airflow resistance, ensuring low pressure drops and providing sufficient power to pneumatic tools.

High pressure resistance – High-quality PU tubing typically has a recommended working pressure of 1.0 MPa (approx. 10 kgf/cm²) at room temperature, with burst pressures reaching up to 3.0 MPa.

2. Exceptional Flexibility and Durability

PU (polyurethane) combines the elasticity of rubber with the rigidity of plastic, giving PU tubing outstanding performance in the following areas:

Superior flexibility and kink resistance – PU tubing can withstand repeated high-intensity bending and can achieve very small bend radii. This is critical for robotic arms that require frequent movement or for compact equipment layouts, as it effectively prevents tangling or kinking that could interrupt airflow.

Excellent abrasion resistance – PU's wear resistance surpasses that of many other plastic tubing materials, making it well-suited for industrial environments where continuous friction with mechanical components occurs, thereby extending service life.

Good oil and chemical resistance – It resists degradation from common industrial lubricants and coolants, preventing tube wall damage due to corrosion.

3. Specialized Variants for Diverse Industry Needs

To meet different application requirements, PU tube for pneumatic systems has evolved into more specialized forms:

Anti-static (ESD) – In electrostatic-sensitive environments such as electronics manufacturing and painting, specialized anti-static PU tubes effectively dissipate static electricity, preventing spark hazards or damage to precision components.

Food-grade – In the food and pharmaceutical industries, FDA-approved PU tubing is available, featuring hydrolysis resistance and antimicrobial properties to withstand rigorous cleaning procedures.

Visual management – Transparent PU tubing allows operators to visually inspect for condensate or contaminants, facilitating rapid troubleshooting.

Cable/hose management – For complex multi-line pneumatic systems, bundled multi-core PU tubes are available for easy identification and quick routing.
