GENTLE PU Polyurethane Tubes｜Flexible PU Hoses for Air Compressors

• Minimal Bend Radius: 7–35 mm bend capability for flexible routing around actuators and in tight spaces without kinking.
• Abrasion, Oil & Solvent Resistant: PU material withstands wear, oil, and common solvents for harsh shop-floor environments.
• Broad Lineup: Multiple OD/ID sizes and roll formats for compressed air, vacuum, and select water-based media.
• Easy Line Management: Five colors—black, red, orange, clear, blue—to simplify identification, inspection, and maintenance.
• Wide Operating Range: Pressure 0–7 kgf/cm², vacuum -750 mmHg, temperature -15–60 °C.
• Applications: Robotic arm pneumatics, cylinder-to-valve runs, vacuum pick/place and venting lines, jigs and distribution modules, compressor in/out lines, lightweight lab/workstation plumbing.

Q1: What is the minimum bend radius?
A: 7–35 mm depending on size, enabling tight routing without collapse or cracking.

Q2: Where are PU tubes commonly used?
A: Air compressors, pneumatic control lines, vacuum systems, automation lines, and general factory environments with oil mist.

Q3: Are PU tubes suitable beyond industrial settings?
A: Yes. Their flexibility and low weight make them ideal for labs, workstations, and educational setups.

Q4: What color options are available?
A: Black, red, orange, clear, and blue for straightforward line identification and maintenance.

Q5: Can PU tubes be used for vacuum service?
A: Yes—rated to -750 mmHg. Also verify fitting sealing and required flow at your size.

Q6: How do PU tubes compare with nylon and rubber hoses?
A: PU = best flexibility for tight bends/moving points; nylon = higher pressure/rigidity for high-pressure or long runs; rubber = strong vibration/shock absorption but heavier and less flexible.

Q7: What real-world issues do PU tubes address?
A: High flexibility and bend endurance reduce twisting and wear on moving axes (e.g., robot arms, tool changers), extending service life and stabilizing performance.
