Moen application and cartridge record
Moen 1255 Duralast Cartridge for Kitchen Faucets
Moen identifies cartridge 1255 for single-handle kitchen faucet using the Duralast platform. Confirm the control layout, operating motion, and installed cartridge before buying; a similar-looking Moen trim is not proof of the valve or faucet beneath it.
Direct answer
The source-backed replacement relationship is single-handle kitchen faucet using the Duralast platform → Moen 1255. This is a reference match, not a promise based on appearance: Confirm that the faucet's official parts list specifies Duralast 1255; older single-handle Moen faucets may instead identify 1225.

Application relationship
Moen's product information places cartridge 1255 in the single-handle kitchen faucet using the Duralast platform application. That relationship is the reason this part is considered here; finish, handle shape, and escutcheon style are not compatibility evidence.
Treat this page as a focused identification record for the cartridge inside the control. The visible faucet or shower trim can be replaced while the underlying valve or faucet platform remains unchanged.
Identify the control before ordering
First confirm one handle controlling flow and temperature. Operate the control and check for this pattern: A single lever controls mixed-water temperature and flow. A different motion points to a different Moen platform even when the trim looks close.
Then verify the generation or internal construction. Confirm that the faucet's official parts list specifies Duralast 1255; older single-handle Moen faucets may instead identify 1225. If documentation is available, use the model number and its official parts diagram rather than a photo-only match.
What the match does not establish
Duralast branding and part documentation matter; a one-handle silhouette alone cannot separate 1255 from 1225. Moen has used more than one cartridge family across products with broadly similar silhouettes, so brand and handle count alone do not settle the choice.
Do not transfer this relationship to another fixture category without an official parts listing. The exact number on the package should match the verified replacement number, including every digit.
Removal-side confirmation
Shut off the appropriate water supplies and relieve pressure before exposing the cartridge. Photograph handle orientation and retaining hardware as each piece comes off; those details help preserve the original setup.
Compare the removed cartridge's body, stem, seals, and retention method with Moen's official material. If the old part is damaged or incomplete, stop and identify the faucet or rough-in valve from its markings instead of guessing from the fragment.
Questions
Before you remove or replace the part
Does every single-handle kitchen faucet using the Duralast platform use Moen 1255?
No blanket fit claim is intended. Moen supports the stated application relationship, but revisions and similarly named products make model, motion, and installed-part checks important before purchase.
Can I identify the cartridge from the handle style?
Not reliably. Handle style is a screening clue only. Confirm one handle controlling flow and temperature, the operating motion, and the cartridge or valve documentation.
Should I remove the old cartridge before buying?
When the model or valve platform cannot be documented another way, removal-side inspection is the strongest check. Shut off water first and preserve the orientation and retaining pieces for reassembly.
