Clear PU Pipe for Pneumatic Air Lines

Problems in an air line usually stay hidden until a machine slows down or a valve sticks. Water, oil and dirt collect inside the tubing, and with coloured pipe you can’t see them. Clear PU pipe lets you see inside the line. You can spot moisture, oil mist or blockages at a glance, long before they damage valves and cylinders. At Wisdo Merchants, we stock clear PU pipe in 6 mm, 8 mm, 10 mm, 12 mm and 16 mm sizes for factories, packaging lines, workshops and maintenance teams across Nairobi and Kenya.

In a pneumatic system, clean, dry air keeps every valve and cylinder working smoothly. Clear polyurethane tubing gives you the same flexibility and push-in convenience as coloured PU pipe, plus a window into the air supply. The size refers to the pipe’s outside diameter, which must match your push-in fitting. As a result, you choose the size that matches your fittings, cut the pipe to length and push it in.

Features and Benefits of the Clear PU Pipe

• See inside the line. Spot water, oil and dirt early, before they reach valves and cylinders.
• Five sizes in stock. Choose 6 mm, 8 mm, 10 mm, 12 mm or 16 mm to match your fittings.
• Flexible and easy to route. It bends around machines and through tight spaces without extra fittings.
• Push-in ready. Its smooth, round outside surface seals cleanly in push-in fittings.
• Neat, clean look. Clear tubing blends into machines and panels where colour isn’t needed.

For maintenance teams, this means faster fault-finding and fewer surprise breakdowns. Meanwhile, owners protect their valves and cylinders from costly water and oil damage.

Technical Specifications

Choosing a size: smaller sizes such as 6 mm and 8 mm suit valves, small cylinders and control lines. Larger sizes such as 10 mm, 12 mm and 16 mm carry more air for bigger cylinders, air tools and supply lines. Always match the pipe size to the fitting size.

Applications of the Clear PU Pipe and How to Use It

• Air lines where you need to check for water or oil, such as after dryers, filters and lubricators
• Packaging, bottling and food processing machines
• Machine building and control panels
• Workshop air supply to air tools
• Replacing cracked, hardened or cloudy air lines

Spotting Moisture in an Air Line

Picture a technician whose cylinders keep sticking on a bottling line. First, they shut off and exhaust the air, then replace a section of the supply line with clear PU pipe. Next, they restore the air and run the machine, watching the clear tubing. After that, they see droplets of water collecting inside, which points to a drain or dryer problem upstream. Finally, they fix the drain, purge the line and confirm the clear pipe stays dry while the cylinders run smoothly again.

Completing the Air System

Clear pipe works best with the right fittings and accessories. Connect it with our push-in air fittings in the same size. For colour-coded lines on the same machine, use our blue air line tubing. On valve and dryer exhausts, fit our perforated steel exhaust silencer to cut noise.

Safety and Handling

• Depressurise first. Shut off and exhaust the air before cutting or disconnecting any line.
• Cut it square. Use a proper tube cutter, since angled or crushed ends don’t seal.
• Push it in fully. A half-inserted pipe can blow out of the fitting under pressure.
• Keep it out of strong sunlight where possible. Long sun exposure can age clear tubing faster.
• Don’t exceed the rating. Keep within the working pressure of the pipe and fittings.

Frequently Asked Questions

Which sizes do you stock?

We stock clear PU pipe in 6 mm, 8 mm, 10 mm, 12 mm and 16 mm outside diameter. Choose your size from the options on this page.

Why choose clear PU pipe over coloured pipe?

Clear pipe lets you see water, oil and dirt inside the line. That makes it easier to catch air quality problems early.

How do I know which size I need?

Check the size marked on your push-in fitting, or measure the outside diameter of your old pipe. The pipe and fitting sizes must match.

How do I cut PU pipe?

Use a sharp tube cutter to make a clean, square cut. Avoid knives or side cutters, which can crush the end and cause leaks.
