Failures of pneumatic automation tubing do not have to be caused by overpressure. Often, failures are the result of gradual degradation of tubing in the environment over time. One of the major factors is the chemical breakdown by moisture. The hydrolysis resistance of TPU is crucial for the use of polyurethane tubing in order to guarantee the mechanical strength of the tubing in humid environments, outdoors or in wet environments within production. For engineers and purchasing departments, the use of hydrolysis resistant polyurethane tubing can be crucial for the reliability of their automation systems and for the maintenance interval and total cost…

The hardness of TPU is one of the most important characteristics for pneumatic tubing. The flexibility of the tubing as well as the air pressure resistance and the lifespan are all affected by the TPU Shore hardness. For engineers, purchasing teams as well as machine manufacturers, the wrong TPU tubing grade can lead to problems such as kinking and leakage, a reduced air pressure or even a burst. Flexible pneumatic tubing for air-stable automation systems are particularly challenged in that they must be sufficiently hard to maintain the air pressure, and at the same time be flexible enough to be…

Polyurethane matters in pneumatic systems because tubing is not just a small accessory; it affects air leakage, actuator response, machine layout, maintenance cost, and replacement frequency. For buyers, engineers, OEM teams, and maintenance departments, choosing the wrong PU Pneumatic tube can lead to poor fitting retention, cracking, kinking, pressure loss, or downtime. A practical selection should consider material type, working pressure, burst pressure, bend radius, temperature range, chemical exposure, and supplier documentation before purchase. What is polyurethane, and why is it used for pneumatic tubing? The general term polyurethane refers to a family of synthetic polymers which are found in numerous…

It looks so simple – a pneumatic tube made of PU. And indeed, the pneumatic tube is probably the part of your pneumatic system that is most frequently contacted by air, by the machine it operates and by human hands. It can have a major effect on air delivery, on machine response, on the risk of leakage, on the cost of maintenance, on safety. And if you are a buyer from the U.S., an engineer, an automation contractor or a procurement person, you will need to check some important criteria of the PU pneumatic tube that you select. Will it withstand the…

PU pneumatic tubes are often used in industrial automation, in fluid control as well as in air delivery systems. As industries strive to reach new levels of efficiency and to increase reliability in 2026, choosing the right PU pneumatic tube is not merely a technical matter. It is a matter of strategic importance with regards to the function and maintenance of a system as well as the return on investment in the long term. This guide to polyurethane pneumatic tubes presents the current types, gives an explanation of the different methods of determining the required size and also contains useful tips…

Pneumatic systems rely on compressed air to power tools, automation lines, and industrial machinery. The performance and reliability of these systems depend on the quality and type of tubing or hoses used to transport air. Choosing the right pneumatic tubing material can impact not only system efficiency but also maintenance costs and operational safety. Each material—whether polyurethane, nylon, polyethylene, or PTFE—offers unique benefits suited for specific conditions such as pressure range, flexibility needs, and chemical exposure. This article explores the most common materials used for pneumatic tubing and hoses, how they perform under various conditions, and why multi-material pneumatic tubing is…
