6 Meters PU Air Hose, 4mm OD x 2.5mm ID Polyurethane Pneumatic Tubing for Compressor and Water Hydraulic Piping, Flexible Fluid Transfer Line（Black）

[Three Sizes] The polyurethane tubing is available in 4×2.5mm, 6×4mm, and 12×8mm (outer diameter × inner diameter), covering a wide range of pneumatic and fluid transfer needs. [Cut to Length] Offered in 3m and 6m lengths for flexible selection and reduced waste. The 3m roll is suitable for short point‑to‑point connections on a workbench or inside machine enclosures. The 6m roll provides longer reach for moving tools, overhead air drops, or connecting remote components across a garage or workshop. [Quality Material] Made of premium polyurethane for superior flexibility. The material remains soft and kink‑resistant even at low temperatures, ensuring uninterrupted airflow or fluid transfer. [Two Color Options] The black polyurethane version contains UV stabilizers, making it suitable for outdoor installation, pneumatic lines exposed to sunlight, and automotive engine bays. The blue option is easy to distinguish from other lines (water, fuel, electrical), simplifying troubleshooting and maintenance in complex machinery. [Wide Compatibility] Reliably works with compressed air, water, light hydraulic oil, diesel, gasoline, and coolant. Use with push‑to‑connect fittings, barbed connectors, or compression fittings. Suitable for air compressor lines, paint spray systems, misting devices, lubrication lines, and pneumatic control circuits.
