Note: This tubing is not intended for drinking water or human consumption. Always use under rated pressure and temperature for maximum service life. Exceeding these limits may cause rupture or premature wear.
Frequently Asked Questions (FAQs)
1. What is the main material of this PU tube?
The tube is made from high-quality thermoplastic polyurethane (PU), known for its superior elasticity, resilience, and chemical resistance.
2. What applications is this tubing suitable for?
Ideal for pneumatic tools, automation systems, air compressors, laboratory gas lines, and general industrial air piping systems.
3. Can it be used for water or drinking applications?
No. The PU air tube is not certified for potable water use and should not be used in any food-grade or drinking water system.
4. What is the maximum operating pressure?
The maximum working pressure is 145 PSI (1.0 MPa) under normal temperature conditions.
5. How does temperature affect pressure capacity?
As temperature rises, the tube’s pressure capacity should be proportionally reduced. Always operate within rated limits for safe long-term performance.
6. Does the tube resist oil and chemicals?
Yes. It has strong resistance to oils, weak acids, alkalis, and hydrolysis, making it ideal for industrial and pneumatic applications.
7. Is it suitable for vacuum systems?
Yes. The tubing can safely handle vacuum systems as well as standard compressed air flow lines.
8. What is meant by “elastic memory” in PU tubing?
Elastic memory refers to the tube’s ability to return to its original shape after stretching, coiling, or bending without permanent deformation.
9. What maintenance is required?
Inspect periodically for surface wear or deformation. Avoid excessive twisting or pulling, and replace immediately if any cracks or air leaks appear.
10. What colors are available?
Standard colors include blue, red, black, and transparent. Custom colors are available for bulk or OEM orders.
