Yellow - PUR tubing 2.5x4 An industrial flexible pneumatic tubing component (MEPU polyurethane series, designed to channel compressed air, inert gases, and non-corrosive fluids across automated pneumatic systems and robotic motion assemblies. It operates via an extruded, high-ester or ether-based polyurethane (PU) formulation that balances high structural flexibility with exceptional kink resistance, allowing smooth fluid transfer during tight-radius bending and continuous dynamic movement. Featuring tight outer-diameter dimensional tolerances for tight-seal push-in fitting integration, high abrasion resistance, and excellent mechanical memory, it ensures leak-free pressure distribution, vibration damping, and long-term durability within dynamic cable carriers and fast-actuating pneumatic automation circuits.
