Moen 1200 and 1225 Cartridge Family
The Moen 1200 and 1225 belong to the same replaceable-cartridge lineage for many older Moen single-handle faucets, but the brass 1200 and plastic-bodied 1225 are distinct service parts.
Direct answer
Moen identifies 1200 as the brass one-handle replacement cartridge and 1225 as the current plastic one-handle replacement cartridge. Moen’s 1225 instructions explicitly cover removal of either a 1200 or 1225, which supports the shared application; still verify a retaining clip and the extracted cartridge shape before purchase.

Family boundary
This family is defined by Moen’s own 1225 service instructions, which tell the installer how to remove an existing 1200 or 1225 cartridge. That source-backed relationship is stronger than color, age, or a seller’s resemblance claim.
It does not include every Moen cartridge. The 1222 is tied to Posi-Temp pressure-balancing shower valves and has a different operating system.
Generation and material distinction
The 1200 is the brass-bodied member associated with older installations. The 1225 is the plastic-bodied replacement sold for one-handle faucets. Their materials and visible details differ even where the service application overlaps.
Treat 1225 as the normal service direction only when Moen’s application and the removed part agree; the family relationship is not permission to install either part in an unidentified valve.
Identification before ordering
Shut off water, remove the handle and trim, and confirm that a horseshoe-style retaining clip secures the cartridge. Compare the stem, body length, port arrangement, and removal procedure with Moen’s instructions.
- Record whether the removed body is brass or plastic.
- Confirm the faucet is a non-Posi-Temp one-handle faucet.
- Do not identify by handle style alone.
Lookalikes and installation implications
A 1222, 1255 Duralast, or two-handle cartridge may appear in the same search results but belongs to another platform. A stuck 1200 can also leave fragments in the valve; confirm the bore is empty and undamaged before inserting the replacement.
Questions
Before you remove or replace the part
Is Moen 1225 the replacement for 1200?
Moen’s 1225 instructions cover removal of either cartridge, supporting that service relationship for applicable one-handle faucets. Confirm the installed valve before ordering.
Are 1200 and 1225 made from the same material?
No. Moen describes 1200 as brass and 1225 as plastic.
Can 1225 replace a 1222?
No. The 1222 serves the Posi-Temp shower platform and is outside this family.
