| Tube Material | Pressure Resistance | Temperature Range | Oil & Wear Resistance | Flexibility | Application |
| PU Tube | Medium-high & burst-resistant | -20℃~60℃ | Normal | Excellent bending resistance | Automatic lines & robotic movement |
| Nylon Tube | High pressure & high strength | -30℃~100℃ | Superior oil & corrosion resistance | Hard, suitable for fixed pipeline | High-temperature & oil-polluted equipment |
| PE Tube | Low pressure resistance | Normal temperature | Medium | Soft & cost-effective | Simple low-pressure pneumatic equipment |
1. Normal-temperature automatic lines & robots: Flexible PU tubes for anti-fatigue performance; 2. High-temperature & low-temperature workshops: Nylon tubes for wide temperature resistance; 3. Oil-polluted machine workshops: Oil-resistant nylon tubes to avoid swelling and damage; 4. Simple low-pressure circuits: Cost-effective PE tubes for conventional ventilation.
1. Frequent bending parts: Replace every 8 months to prevent fatigue burst; 2. High-temperature & oil areas: Annual overall replacement to avoid aging embrittlement; 3. Avoid forced stretching and sharp cutting during installation; 4. Do not mix old and new tubes to prevent joint loosening and leakage.
