Meister 9930190

The only fully specified hose on this shelf

Length 20 m. Inner diameter 19.05 mm. Wall thickness 2.9 mm. Maximum working pressure 9 bar. Burst pressure 18 bar. Weight 250 g per metre. Colour, muted yellow with green stripes.

That is six measurable figures. The next best listing here publishes three, and one publishes none.

The number the rest of the shelf is missing

9 bar working, 18 bar burst.

Six of the seven hoses on this shelf publish a burst pressure — 20, 22, 30 bar — and nothing beside it.

Burst pressure is the point of failure. It describes a margin, not an operating point, and on its own it is close to useless for choosing a hose.

This is the only listing here that states both, and the pair is worth carrying to every other page on this shelf: the burst figure is twice the working figure, on this product. That is one measurement from one manufacturer. It is not a law, and it is the only evidence this shelf contains.

3/4 inch, and what it is for

Every other hose here is 1/2 inch. This is 19.05 mm.

Bore decides flow. At the same pressure, a wider hose delivers more water and loses less of it to friction over a long run — which is why the listing names pumps, domestic water systems and long transport distances rather than watering a border.

The costs are real:

It is heavier. 250 g per metre times 20 metres is 5 kg of hose empty, before the water in it. Full, a 3/4 inch hose holds roughly twice the water of a half-inch one of the same length.

It is stiffer. A 2.9 mm wall on a 19 mm bore does not fold into a small coil.

And it needs 3/4 inch fittings. Most garden quick-connectors, guns, sprinklers and reels are sized for half-inch hose. Buying this means buying its couplings too.

The materials statement

“Regenerate-free material, that is, free of cadmium, barium and lead.”

Virgin PVC rather than reground scrap, and named against three heavy-metal stabilisers that turn up in some recycled PVC.

No other listing on this shelf says anything about what its plastic is made from. One states compliance with the EU food-contact regulation, which is a different and narrower claim about migration; this is a statement about the feedstock.

Spiral tricot weave

The reinforcement: a knitted rather than braided structure, laid in a spiral.

The listing’s claims for it are abrasion resistance on all surfaces and resistance to kinking and twisting — which is what a hose dragged 20 metres across paving, gravel and lawn actually needs.

It is also the reason for the weight. A heavier reinforcement and a thicker wall are the same decision, and 250 g per metre is the price of it.

Availability

From 44 € to 57 €, that being the spread across the German, French, Italian and Spanish Amazon stores on the day of the survey.

Beyond the euro zone, the American and British Amazon stores price it in their own currencies, which the spread above sets aside.
