The documented replacement
SharkNinja's US record lists NC301 as compatible with Creamerizer paddle 726KKU300. The paddle, outer-bowl lid 725KKU300 and pint lid 728KKU300 are separate parts. Match both the machine model and the component you need; a listing that says only ‘CREAMi blade’ or ‘CREAMi lid’ is not enough.
Compatibility ledger
MODEL-SPECIFIC| Item or model | Fits | Verdict | Research note |
|---|---|---|---|
| 726KKU300 — Creamerizer paddle | NC301 explicitly listed | Fits | Manufacturer-listed compatibility, not a FitCheck Lab physical test. Check the selected seller's actual part and variant. |
| 725KKU300 — outer-bowl lid | NC301 explicitly listed | Fits | The processing lid is a separate component. Do not assume a listing includes the paddle. |
| 728KKU300 — pint lid | NC301 explicitly listed | Fits | This is the pint's storage lid, not a replacement for the processing lid or paddle. |
| A generic ‘CREAMi blade’ with no exact model list | NC301 compatibility unresolved | Verify model | Brand name, appearance and a copied part number do not establish third-party compatibility. |
Start with the machine label, not the marketplace title
This guide covers the US NC301. Copy your complete machine model before shopping, including any suffix. The official 726KKU300 page also names NC299AMZ, NC300 and specific NC301 variants, but that does not make every product carrying the CREAMi name equivalent. For a different model, check its own parts record. We do not extend this list to Deluxe or Scoop & Swirl machines, or claim that every unlisted model is physically incompatible.
Which part is actually missing?
Use the component comparison above before placing an order. A missing paddle calls for checking the paddle record; a missing processing cover calls for checking the outer-bowl lid record. Ninja describes 725KKU300 as the lid that locks onto the outer bowl before processing. Its compatibility list includes NC301, but it is a separate product record from 726KKU300. Read the package contents rather than assuming that a photograph showing an assembled lid promises both components.
A pint storage lid is not a processing-lid substitute
The NC301 product page distinguishes the supplied pints with storage lids from the outer bowl and its lid. The 728KKU300 record identifies a pint lid and lists NC301. This is why a cheap listing headed ‘replacement lids’ may solve a storage problem but not replace the part needed on the processing assembly. First identify the component's job, then confirm its code. Do not buy a complete container set solely because the search result includes the word ‘lid.’
If the machine will not run, do not diagnose it from this parts list
A documented fit is not proof that buying that part will repair your machine. If you already have the paddle and lid but the unit will not operate, use the model-specific instructions and contact Ninja support before ordering. Describe the indicator or behavior, the full machine model, which component was changed and the code on the replacement packaging. This page does not diagnose an interlock, motor or other internal fault, and does not recommend bypassing a safety mechanism or modifying a part.
Before checkout: verify the selected variant
Our purchase check is component name, complete model, part number, package contents, then seller terms. On Amazon, the search may mix genuine parts, third-party replacements and unrelated accessories. Open the selected offer and verify that its compatibility statement applies to that exact variant. A seller mentioning 726KKU300 does not make its item an official Ninja part. If the details conflict, ask the seller or Ninja to resolve them; do not substitute a visual guess.
Evidence and image boundary
The official US product records linked below were checked on September 18, 2026. This is documentary research, not a hands-on review, a physical fit test or an individual fault diagnosis. The diagram maps component names to published part codes; it does not show product geometry or installation steps. We make no claims about current price, stock, ratings or the performance of third-party alternatives.
