Corrugated PVC Reinforced Flexible Ducting is a durable, lightweight hose designed for air, dust, fume, and light material handling applications. Manufactured from high-quality PVC with an embedded steel wire helix, it offers excellent flexibility and crush resistance while maintaining a smooth internal bore for optimal airflow. The transparent construction allows easy visual inspection during use.

Key Features:

Material: Flexible PVC with embedded steel wire helix reinforcement.
Temperature Range: -20°C to +80°C (intermittent up to +85°C).
Wall Thickness: 0.7 mm to 1.4 mm depending on diameter.
Bend Radius: Approximately equal to internal diameter.
Construction: Corrugated outer wall with smooth internal bore for reduced friction loss.
Flexibility: Highly flexible, crush-resistant, and lightweight design.
Colour: Black/Clear.

Engineered with a corrugated outer wall for high flexibility, this PVC ducting is reinforced with a steel wire helix to maintain shape under vacuum or light pressure. The smooth inner bore minimises airflow resistance, making it efficient for conveying air, dust, vapours, and light particles. Its crush-resistant design allows it to perform reliably in demanding conditions while remaining easy to handle and install.

Suitable for extraction systems, ventilation ducts, woodworking machinery, welding fume extraction, and light-duty material handling, this hose is widely used in workshops, manufacturing plants, and maintenance facilities. The PVC body has a durable construction guarantees long service life under normal operating conditions.

How to measure ID

Measure the pipe, not the old hose

Heat and age make a used hose swell and go out of round. Take your reading across the metal outlet the hose slides onto — that measurement is your ID.

Use vernier calipers

Set the outer jaws across the widest point of the pipe. A tape measure round a curve reads low by a millimetre or two — enough to buy the wrong size.

Take three readings, keep the largest

Rotate 60° between each. If they disagree the pipe is oval; size to the biggest figure so the hose still seals.

Round to the nearest listed bore

Never go up: a bore wider than the fitting will not grip, whatever the hose is made of. If you land between listed sizes take the smaller bore, and secure it with a clip.

Order by ID, always. Every hose on this site is listed by internal diameter. OD is given for clearance only — it changes with wall thickness and ply count, so it is never the ordering size. On reducers, quote both ends, largest first.

Frequently Asked Questions.

Answers to the questions we’re asked most about sizing, fitment and performance.

Still can't find your answer?

What is it used for?

Air, dust, fume and light material handling, and pond and pump work. The embedded steel wire helix gives crush and vacuum resistance while keeping a smooth internal bore.

What sizes and lengths do you supply?

Available in internal diameters from 19mm to 51mm, lengths from 1 Metre to 50 Metres (Full Coil), in clear and black. Order by internal diameter to match the outside diameter of the barb or spigot it pushes onto. Full coils work out considerably better value per metre than cut lengths.

What pressure and temperature is it rated for?

Working pressure runs from 5 bar on the smallest bore down to 3 bar on the largest, with burst pressure from 15 bar down to 9 bar across the 19mm to 50mm range. The operating range is -10C to +65C, built to PVC. PVC also stiffens noticeably in cold weather, so uncoil it gently on a frosty morning rather than pulling it straight.

Can I use it on the suction side of a pump?

Yes - that is what the embedded steel helix is for. It holds the bore open under negative pressure, so it works on both the suction and discharge sides. This is the key difference between it and layflat hose, which collapses immediately under suction.

Is it safe for drinking water or food use?

No - this is a general-purpose industrial hose and is not certified for potable water or food contact. If you need a certified food-grade or potable hose, tell us the application and we will point you at an appropriately certified product.

How do I connect it?

Push it fully onto the barb or spigot - warming the end in hot water makes larger sizes far easier - and secure with a stainless worm drive clip. On higher-pressure runs, two clips at right angles give a better grip. Cut the hose square so it seats evenly.
