Garden hoses
KÄRCHER PrimoFlex 2.645-138.0
A well-known hose whose entire published description is one raw database field.
What is published
One feature line.
A power-source field, with the value “hand-operated”.
That is a catalogue attribute — a field a distribution system fills for every
product it carries, whether or not it means anything — and here it has been
published with its field name still attached, on a garden hose.
There is no other description.
What that leaves
A length: 20 m. A diameter: 1/2 inch. A part number: 2.645-138.0.
No layer count. No burst pressure. No working pressure. No temperature range.
No wall thickness. No weight per metre. No material.
Every other product on this shelf publishes at least three of those. The most
recognised brand here publishes none.
What this page refuses to do
Fill the gap.
It would be easy to write that a hose from a well-known pressure-washer
manufacturer is presumably well made, and that a mid-priced 20-metre half-inch
hose presumably has a braid and presumably handles mains pressure.
Presumably is not a specification, and a site that supplies one from a brand
name is a site whose specifications cannot be trusted anywhere else.
The product is undescribed. That is the finding.
The part number, which is the one useful thing
2.645-138.0, carried here as 26451380.
That is the maker’s own reference, and it is how this hose is actually ordered:
from a dealer, from a spares list, or as a replacement for the identical hose
that came with something else.
Somebody replacing a known hose with the same hose has everything they need. It
is the person choosing between this and six alternatives who has nothing.
For comparison, on this shelf
Two hoses publish a temperature range: −10 to +50 °C and −25 to +60 °C.
Three publish a layer count: four, six, and three.
Six publish a burst pressure: 20, 30, 22, 18 bar, and two stated differently.
One publishes a working pressure, a wall thickness and a weight per metre.
This one publishes a length and a diameter.
Availability
From 26 € to 31 €, 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.
