How to measure OD

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.

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.

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.

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.

Still can't find your answer?

What is it used for?

Joining two hoses of the same internal diameter in low-pressure water, pond, ducting and general workshop plumbing.

How do I size one?

Match the barb outside diameter to your hose internal diameter. It should need a firm push to go on - warming the hose end in hot water makes a tight fit far easier. If it slides on loosely it is too small. Available in outside diameters from 8mm to 102mm, in black, white, blue and red.

Do I need clips?

On anything pressurised, or anything that matters if it comes off, yes - one each side. The barb resists pull-off but does not seal on its own once the hose relaxes with age and temperature. A stainless clip is cheap insurance.

When should I use metal or silicone instead?

For anything pressurised, hot, or carrying fuel or oil. Plastic has neither the temperature range nor the strength for engine bay work. We stock aluminium beaded and unbeaded joiners from 8mm to 102mm and silicone couplers from 13mm to 152mm for those applications.

What is it made from?

ABS plastic, thick walled. That gives good strength for a plastic fitting, resistance to corrosion in constant contact with water, and a low cost. What it does not give is temperature range or strength for pressurised systems.

What temperature will it take?

It is a general-purpose ABS fitting for ambient and low-temperature use. Keep it away from engine bays, hot process fluid and exhaust heat, where you need metal or silicone. If you are unsure about your temperature, tell us and we will confirm.
