Faucet part identification

Identify faucet cartridges and repair parts
with evidence.

Use the fixture, handle arrangement, markings, and measurements to narrow a cartridge or repair part—then confirm the source-backed application before you buy.

Guided lookup

Narrow the part before you buy it

Enter any number or marking you have, then add the fixture details you can confirm. Leave unknown fields blank; the result list explains which record to check next.

A safer lookup sequence

Three checks before a replacement becomes plausible

Cartridges that share a color or silhouette can differ by diameter, port layout, stem interface, production generation, or valve function. Build the match from more than one clue.

  1. 01

    Start with the fixture

    Separate kitchen, lavatory, shower, Roman-tub, and outdoor systems before comparing the removable part. The same brand can use different valve families in each context.

  2. 02

    Add independent clues

    Combine a model or part marking with handle arrangement, valve generation, overall length, body diameter, port pattern, thread, or stem interface.

  3. 03

    Open the evidence record

    A shortlist is not a fit claim. Read the linked application record, common mix-ups, source trail, and confirmation sequence before ordering or disassembly.

Browse by manufacturer

Start where the marking leads

Brand narrows the catalog, but it does not settle the fit. Each guide points to the valve families, fixture contexts, and generation checks that still matter.

When there is no model number

Use a bounded comparison, not an image guess

A matrix groups parts by the attributes that actually separate them: control type, handle count, valve generation, broach, diameter, thread, ports, or connector geometry.
