Choosing the right polyurethane tube for your pneumatic setup isn't just about grabbing the cheapest spool. You need enough length for the run, a pressure rating that matches your system, and a material that works with the fluid you're moving. These two PU options take very different routes: a short black line that pairs with air compressor fittings, and a long transparent hose designed for air, water, lubricating oil, and pneumatic or robotic controls.
Quick Verdict
Choose the black 1/8" PU tubing if you need a compact, lower-priced line for air compressor fittings, brake lines, or water transfer. Pick the transparent 50-meter hose if you need a long, highly transparent run for pneumatic controls and robotic systems, and you're comfortable with the higher price.
| Product | Price Bar | Price | Length | Color | Key Spec |
|---|---|---|---|---|---|
| 1/8\" OD Pneumatic Tubing Pipe, Black, 10 Meter/32.8ft | PU Air Tubing Pipe, Air | $9.75 | 10 m / 32.8 ft | Black | 1/8\" OD, 363 psi max | |
| Polyurethane Flexible Tubing Pneumatic PU Pipe Tube Hose -Air Chemical Fuel Oil | $92.30 | 50 m | Transparent | 6x4 mm, 0-1 MPa operating |
Where Each Product Wins
The black 1/8" PU tubing is the pick when:
- You want a lower upfront price.
- Your system needs a maximum pressure rating of 363 psi.
- You need a working temperature range from -4°F to 176°F.
The transparent 50m PU hose is the pick when:
- You need far more line length.
- You want to see fluid flow through highly transparent material.
- Your application involves twisting, folding, or robotic movement.
Product Notes
1/8\" OD Pneumatic Tubing Pipe, Black, 10 Meter/32.8ft | PU Air Tubing Pipe, Air
This black PU line is a compact 10-meter (32.8-foot) option for air compressor fittings, brake line tubing, and water fluid transfer. Its 363 psi maximum pressure rating and -4°F to 176°F working temperature range make it suitable for moderate-pressure tasks where you don't need a huge spool. The 1/8\" outside diameter is fairly narrow. The limitation is the short length: a 32.8-foot run may not be enough for a large shop layout, and the black exterior makes it harder to see if fluid is flowing or if a blockage occurs.
Polyurethane Flexible Tubing Pneumatic PU Pipe Tube Hose -Air Chemical Fuel Oil
This transparent PU hose is a 50-meter continuous roll with a 6x4 mm OD/ID, designed for air, water, lubricating oil, and pneumatic or robotic controls. The high transparency lets you monitor flow, and the material is described as flexible enough to handle twists and folds without creases, making it a good fit for moving robotic arms or control lines that need to bend repeatedly. Its operating pressure of 0-1 MPa is fine for many pneumatic circuits, but it does not match the 363 psi maximum pressure rating of the smaller tube. That lower pressure ceiling is the main constraint if you're feeding high-pressure air equipment.
Final Choice by Use Case
For a short, moderate-pressure run like a brake line, air compressor fitting, or water transfer task, the black 1/8\" PU tubing is the simpler, lower-priced option. For long runs where you need plenty of slack, visible flow monitoring, and resistance to repeated bending, the transparent 50-meter PU hose is the stronger choice.
