Polyurethane (PU) tubing is highly regarded in the industry for its exceptional flexibility, kink resistance, and durability. This material is well-suited for pneumatic applications due to its resilience and ability to withstand repeated flexing without damage. Polyurethane tubing combines the best properties of both rubber and plastic, making it an ideal choice for applications where other materials might fail.
The black color provides UV resistance, ensuring longevity in outdoor applications. This tubing is commonly used in pneumatic systems, robotics, fuel lines, and fluid transfer lines where flexible and durable tubing is required.

Maintenance
Polyurethane tubing requires minimal maintenance. Regular inspection for any signs of wear, tear, or chemical damage is recommended, especially in highly demanding applications. If the tubing is used in environments with high exposure to sunlight, ensure that the UV-resistant variant is used to prevent degradation.
