You need it, you are not holding it
You know roughly what you are after but the part is not in front of you. Type it — a name, a rating, a model number. You do not need a photo to start.
PARTSIGNAL
“Discontinued” rarely means the part is gone.
A wholesaler wrote off a fan as discontinued. It was still being made — in Germany, under a different number, and the manufacturer confirmed it in writing. Describe what you need, or photograph it. PartSignal works out what it actually is, whether a working equivalent still exists, and whether one is already sitting documented and unused.
When to use PartSignal
PartSignal answers one question: what is this part, and what else fits. For working out why something is broken, Describe or Remote will get you further.
You have it, you cannot name it
A valve, a fan, a thermostat head, clearly part of the system, but nothing legible on it. Photograph it and the nameplate if there is one.
A wholesaler said discontinued
Most parts written off that way are still made, often under another brand or number. That is the case PartSignal was built around.
Before you buy the wrong one
One checked answer beats ordering three and hoping. And if we already hold a working one, you will see it before you buy new.
What helps
Whatever you have is enough to start.
None of this is required, and you do not need the right technical words. Each one just narrows it down faster.
a description in your own words — or a photo
a photo of the nameplate, if the part is in front of you
model, article, RSK or VVS number, if any are legible
rough measurements, or the rating you need
what the part has to do, and where it sits
How it works
Our own shelf first, then the catalogue, then the market.
Describe the part, or photograph it — either is enough to start
We check what we hold ourselves. If it is on our shelf, you see it straight away, free
If not, the catalogue works out what it actually is, including the same part under another brand or number
A professional verifies the match before you order anything
Nothing found is an answer too — we can keep looking for twelve months and write when it turns up
What PartSignal does not promise
A candidate, not a guarantee.
PartSignal never confirms on its own that a part fits, is in stock, or is safe to install. Identification is at component level, not an official manufacturer endorsement, and a professional checks it before anything is ordered.
Got one you cannot find?
A sentence is enough to start. If it exists, we will tell you where — and if it does not, we will tell you that too.
