Features
The Coiling Tube is suitable for piping of air guns, air screwdrivers and other air tools. Also,piping of movable parts can be achieved within limited spaces without distorting the joints. There are the urethane type featuring flexibility and the nylon type excelling in restoring force.
Applications
● Pneumatic systems, air tools
● Vacuum
● Automation
● Plant Instrumentation
● Paint supply lines
● Construction applications
● Motion control devices
Advantages of Polyurethane Over Other Materials
Compared with traditional PVC or rubber air hoses, polyurethane tubing offers several performance benefits.
Polyurethane has significantly better abrasion resistance, allowing it to withstand repeated movement and friction in industrial environments. It also maintains flexibility even at lower temperatures, which helps prevent cracking or hardening during operation.
In addition, polyurethane tubing typically has higher tear strength and longer service life, reducing the frequency of replacement in pneumatic systems.
These properties make PU tubing one of the most preferred materials for modern pneumatic applications.
