How to measure OD

1

Measure across the outside

Rigid pipe, tube and joiners are sized by the outer wall, because that is the surface a hose seals against. The bore and wall thickness follow from it — they are not the ordering size.

2

Use vernier calipers

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

3

Take three readings, keep the largest

Rotate 60° between each. If they disagree the tube is oval; size to the biggest figure so the hose still clamps down evenly.

4

Match the hose to this OD

The hose sleeves over the tube, so the hose you want is the one whose internal diameter equals this outside diameter. A 51 mm tube takes a 51 mm ID hose.

Order by OD, always. Tube, rigid pipe and joiners are listed by outside diameter — the surface the hose clamps onto. Pair one with a hose of the same ID. On reducers, quote both ends, largest first.

Frequently Asked Questions.

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

What is it for?

Joining two runs of PU polyurethane ducting of different diameters, or stepping a duct down to a smaller machine spigot, in dust extraction, woodworking, agricultural ventilation and general industrial air handling.

What size pairings do you stock?

Stepped pairings from 65mm to 50mm up to 150mm to 125mm, including 80mm, 100mm and 125mm as the larger end. Order the large diameter first and the small one second, matching the bore of the ducting on each side.

What is it made from?

ABS plastic, 3D printed, chosen for toughness, impact resistance and a long service life. It is non-corroding and light, so it does not load the duct run.

How does it hold?

The ribbed male profile grips inside the duct wall, and a clamp over each side pulls it tight. No adhesive or sealant required, and it comes apart again when you reconfigure the run.

Will reducing the duct size cost me airflow?

Yes - every reduction raises resistance and drops flow, and the effect is larger than people expect. Never neck down below the fan or machine outlet diameter, and reduce as close to the end of the run as you can rather than at the start.

How do I fit it?

Push each duct fully onto its spigot, seat it past the ribs, and secure with a worm drive clip or ducting clamp. Support the duct either side so the connector is not carrying the run.
