An air hose is a tube which transports pressurised air to pneumatic actuators, valves, tools and other devices. A robust and reliable air hose is absolutely essential to maintaining a consistent airflow. A wide range of materials can be used to create the tubing such as polyurethane, rubber, PVC and nylon. Selecting the correct material to suit the application and environment is important to ensure a long service life.

Application: The requirements with respect to pressure, temperature, flexibility and environmental influences differ from industry to industry. Users frequently underestimate the risks: around 90% of all cases of damage can be traced back to the wrong choice of tubing or tubing materials. This can not only result in energy losses, but also machine downtimes. It is especially important to find a reliable and cost effective product that prevents tubing degradation during operation.

Hydrolysis resistant and suitable for water applications. Combination suitable for use in clean rooms, corrosion resistant thanks to 100% polymer construction. Reliable:As an expansion to our popular PUN-H tubing it is suitable for wet areas with water contact to 50ºC without cracking through hydrolysis. Highly Versatile: Not only is the kink-resistant PUN-H easy to install, its resistance to hydrolysis and microbes make it a perfect choice for the food industry. Black version is UV-resistant and can be used outdoors.
