Norgren PU2-0704025C Polyurethane Tube - 4mm O/D

Material and flexibility: PU2 tubing uses polyurethane to deliver excellent mechanical properties and industry-leading flexibility. The material resists kinking under dynamic load and maintains consistent inner bore over time, reducing variability in flow and actuator response. This makes it well-suited for short, curved runs on automated pick-and-place stations and conveyor spurs. Size, weight, and installation efficiency: With 4 mm outer diameter and 2.5 mm inner diameter, the tube integrates with compact pneumatic fittings and small actuators. The 25 m length provides extended runs between manifolds and minimizes the need for joins, lowering leak points and installation time. The 1 kg weight per spool keeps handling practical in field updates. Operating range and reliability: The tube performs across -40 to 60 C (-40 to 140 F) and -0.95 to 10 bar (-14 to 145 psi), covering cold rooms, outdoor lines, and general factory floors. This broad tolerance ensures stable pressure delivery to cylinders and actuators even with temperature swings and pressure fluctuations common in packaging and automotive components. Mechanical resistance and bend performance: A minimum bend radius of 6 mm supports tight routing in cramped enclosures while preserving flow and reducing stress concentrations. The 4 mm OD resists collapse at typical system pressures and maintains a consistent ID for repeatable performance on multi-axis movers. Compatibility and ease of use: The black PU2 tube is compatible with standard pneumatic fittings, push-to-connect connectors, and valve manifolds, enabling rapid integration into existing lines. Cut-to-length installation, clear color coding, and supplier-backed datasheet-guided guidelines streamline commissioning and field maintenance. Durability and ROI: Polyurethane tubing combines abrasion resistance with fatigue endurance, delivering longer service life in high-cycle applications. Its stable performance supports higher line uptime, improved actuation repeatability, and predictable maintenance across manufacturing lines, robotics workstations, and packaging systems.
