Overview
Understand the PU product family
PU ester-base polyurethane tubing is available in listed metric and inch sizes for air piping. Compare outside and inside diameters, roll lengths and bend-radius data.
Selection approach
Select a listed outside/inside diameter pair and roll length, then specify the required color. Assess working pressure separately: the table gives burst pressure at 20°C.
All values shown below are traceable to the reviewed Catalog source. Missing information is not inferred.

Technical confirmation notes
- The 24/30 bar figures are burst pressures at 20°C, not safe working pressures. Do not use them as operating ratings throughout the temperature range.
- Specify a listed base size with its roll length and required color. The order example is a format guide, not an additional model.
- The size table gives the minimum bending radius at 20°C. Confirm routing and working conditions for the installation.
