Polyurethane Pneumatic Tubing Key Features

• Flexible PU Construction: Supports convenient tubing routing and installation in compact pneumatic equipment.
• Abrasion Resistance Material: Polyurethane material offers good resistance to surface wear during normal handling and installation.
• Four Size Options: Provides different inner and outer diameter combinations for various pneumatic connection requirements.
• Compressed Air Compatibility: Suitable for compressed air connections in compatible miniature pumps, compressors, and pneumatic systems.
• Specified Working Pressure: Supports a working pressure range of 0–10 bar at 20°C, subject to proper connections and operating conditions.
• Transparent Design: Allows visual inspection of the tubing and air line.
• 1-Meter Length: Each tubing variant is supplied in a 1 m length for equipment assembly and pneumatic connections.

Size Selection & Installation Guidelines

• Inner Diameter Selection: Select the appropriate tubing inner diameter based on the pump port and connection requirements.
• Outer Diameter Selection: Confirm the tubing outer diameter matches the pneumatic fittings or connectors used in the system.
• Model Selection: Choose one of the four available ID × OD combinations. Inner and outer diameters are fixed pairs and cannot be selected independently.
• Tubing Installation: Route the PU tube without excessive bending, twisting, or stretching to avoid restricting airflow.
• Connection Security: Ensure all tubing connections are properly secured and suitable for the intended working pressure.

Important Notes

• Confirm the selected tubing dimensions are compatible with the pump ports, pneumatic fittings, and connection interfaces before ordering.
