Single Tubing and DUO Tubing Design
Standard single tubing
The standard PUN-H version consists of one polyurethane tube. It is suitable for individual pneumatic connections where a single line is routed between components such as valves, cylinders and air preparation equipment.
DUO twin tubing
The PUN-H-DUO version consists of two tubes joined together to form a pair. The pair can be cut to the required installation length at both ends. This arrangement can simplify routing where two pneumatic lines need to follow the same path.
Operating Pressure and Temperature
For the documented 3 mm to 16 mm standard tubing and DUO configurations, the temperature-dependent operating pressure range is stated as -0.95 bar to 10 bar. The operating pressure across the complete temperature range is stated as -0.95 bar to 6 bar.
For water applications, the manufacturer specifies a maximum operating pressure of 3 bar at temperatures from 0°C to 60°C, with temperature-dependent limits applying. Always refer to the manufacturer’s pressure-versus-temperature diagram for the selected tube size and operating medium.
The documented ambient temperature range for these configurations is -35°C to +60°C. Actual operating suitability depends on the tube size, pressure, temperature, medium and installation conditions.
Suitable Applications
- Pneumatic automation systems
- Industrial machinery and equipment
- Compressed-air distribution lines
- Vacuum handling systems
- Machine tools and production equipment
- Robotics and automated assembly equipment
- Moving machine installations and energy chains
- Suitable water applications within the manufacturer’s limits
- Equipment requiring organised single or twin pneumatic lines
Benefits for Industrial Installations
- Flexible routing helps connect pneumatic components in compact machinery.
- Different outside diameters support a range of connection requirements.
- DUO tubing keeps two lines together for more organised routing.
- Colour choices can help identify lines during installation and maintenance.
- Hydrolysis resistance supports suitable water-related applications.
- Energy-chain suitability supports selected moving machine installations.
How to Select the Correct Plastic Tubing
Choose the tubing according to the machine design and operating conditions. Check the following points before ordering:
- Outside diameter: Match the tube outside diameter to the compatible push-in or other specified fitting.
- Inside diameter: Check the internal diameter against the required airflow and system performance.
- Single or DUO design: Select a single tube for an individual line or DUO tubing where two lines need to be routed together.
- Operating medium: Confirm whether the application uses compressed air, vacuum or water.
- Pressure and temperature: Verify the manufacturer’s limits for the exact size and medium.
- Bend radius: Follow the specified minimum and flow-relevant bending radius to avoid restricting the line.
- Colour: Select the required colour for line identification and installation requirements.
- Fitting compatibility: Confirm that the selected fitting is designed for the tube’s material and outside diameter.
Industrial Buyer Guide
Industrial buyers should confirm the required tube size, quantity, colour, single or DUO configuration and operating medium before requesting a quotation. For replacement requirements, compare the existing tube’s outside diameter, inside diameter and wall thickness rather than selecting by colour or appearance alone.
For machine builders and maintenance teams, it is also important to verify the fitting compatibility, operating pressure, temperature range and routing requirements. Allarakhu & Sons can assist with product enquiries and availability checks for industrial customers.
