American Standard identification hub
American Standard faucet part identification
A model-led guide to American Standard ceramic cartridges, pressure-balance valves, and fixture-specific repair parts.
Direct answer

Fit facts
What identifies this match
Use these details together. One matching feature does not establish compatibility.
- Service number clue
- Many American Standard repair-part identifiers begin with M followed by digits and a suffix
- Suffix importance
- The complete suffix is part of the service identifier and should not be dropped
- Shower families
- Pressure-balance and thermostatic shower systems use distinct control components
- Faucet distinction
- Single-control and two-handle ceramic valve applications follow different parts diagrams
- Generation risk
- Long-running product lines may have updated repair parts or production changes
- Best evidence
- Model-specific repair-parts sheet plus removed-part comparison
Find the product model
Check installation paperwork, receipts, packaging, and the product page. Use the full model and finish suffix when locating American Standard's repair-parts drawing.
Keep M-numbers complete
An M-prefixed number can identify a repair assembly, but similar digits are not interchangeable. Preserve punctuation and suffixes such as the characters following the numeric core.
Identify the valve function
For showers, determine whether the system is pressure balancing, thermostatic, or a separate volume control. For deck fixtures, distinguish one-handle mixer cartridges from hot and cold ceramic valves.
Resolve production changes
A familiar collection name can survive internal revisions. Check the official parts sheet's date or notes and accept a successor only when American Standard documents the replacement relationship.
Constrain by fixture context
Separate kitchen, lavatory, roman-tub, and shower applications before comparing parts. Handle count, installation location, and hot or cold orientation are useful eliminators.
Decision path
Identify the model, obtain its repair-parts diagram, and copy the full service number. Compare the original part's function, stem, seals, ports, and dimensions, then verify any updated number through official support.
Independent reference
FaucetClarity is independent and is not affiliated with or endorsed by American Standard. Product and repair-part names are descriptive references; current manufacturer documentation should determine fit.
Questions
Before you remove or replace the part
Can I search only the digits in an M-number?
Use the complete identifier. Its prefix and suffix can distinguish the exact repair assembly.
Are hot and cold cartridges always the same?
No. Rotation and application may differ, so confirm the side and official part listing.
Does a collection name prove the internal part?
No. Use the full model and its repair-parts drawing, especially across production changes.
