Moen identification hub
Moen faucet and shower part identification
A source-led path from fixture clues to the correct Moen service part, without treating a similar-looking cartridge as proof of fit.
Direct answer
Start with the model number or Moen's product-identification resources, then match the fixture type, control style, cartridge number, and generation before buying.
Fit facts
What identifies this match
Use these details together. One matching feature does not establish compatibility.
- Strongest clue
- A model number from the paperwork, box, receipt, or product page
- Common cartridge families
- 1222 pressure-balancing, 1225 single-handle, 1255 Duralast, and 1200 legacy brass applications
- Shower distinction
- Posi-Temp and Moentrol controls are not interchangeable merely because their trim looks related
- Fixture context
- Kitchen, lavatory, roman-tub, and shower products use different service-part paths
- Finish clue
- Finish codes help identify visible trim but do not by themselves identify the valve behind the wall
- Purchase rule
- Confirm the official parts diagram or cartridge application before ordering
Find the model before the part
Search old installation paperwork, the retail listing, and Moen's identification guidance first. A collection name or finish is useful context, but the model number is the better route to the exploded parts view.
Read Moen number clues carefully
Moen service cartridges commonly appear as four-digit numbers such as 1222, 1225, and 1255. Those numbers identify cartridge families, not every faucet that looks capable of accepting them.
- Record every number molded or stamped on the removed part.
- Keep suffixes and finish codes attached to the full faucet model when searching.
Separate valve systems
For showers, identify how the control operates before removing trim. Posi-Temp typically uses rotation for temperature control, while Moentrol is a different valve system with pull-on operation; an official valve or trim compatibility listing should settle the application.
Account for generation changes
A long-lived collection can span more than one internal design. Compare stem shape, retaining method, overall dimensions, and the official service sheet rather than assuming that a current cartridge replaces every older version.
Use the fixture context
A cartridge found in a widespread faucet, a single-handle kitchen faucet, or a pressure-balancing shower valve may share brand markings while serving a different hydraulic layout. Classify the fixture and handle count before comparing parts.
Decision path
Identify the model if possible, open its official parts diagram, note the named valve or cartridge, and compare the removed part. If the model remains unknown, use Moen's identification help and measurements; buy only after the application and physical evidence agree.

Questions
Before you remove or replace the part
Can appearance identify a Moen cartridge?
No. Appearance can narrow candidates, but the fixture system, operation, markings, dimensions, and official application must agree.
Is 1222 the same as 1225?
No. Moen lists them as different cartridge families for different applications.
Where should I look for the model?
Check paperwork, receipts, the original product listing, packaging, and Moen's product-identification resources.
