QT Replacement Parts 24OZ Cups For Nutri bullet 600w & 900w

The Verdict

If you’ve dropped your Nutribullet cup one too many times or the threads finally gave out after a year of daily smoothies, you already know the sting of OEM replacement pricing. The QT 24oz cups undercut that dramatically — but does “compatible” actually mean “identical”? I tested these against a stock Nutribullet 600W base and put them through two weeks of morning shakes. Here’s the straight story.

What’s in the package

You’re getting two 24-ounce Tritan plastic cups, two sealing storage lids, and that’s it. No blade base, no gasket rings, no extra parts. As shown in the product image, these are the tall, tapered cups with the standard Nutribullet thread pattern. The packaging is basic — don’t expect retail-grade presentation, but that’s not why you’re here.

Build quality and real-world performance

The cups are made from Tritan copolyester, which is the same BPA-free material Nutribullet uses in their original cups. That matters — cheaper knockoffs often use polycarbonate or acrylic that clouds up, picks up odors, or worse, cracks under the torque of a 900W motor. These QT cups feel dense and rigid in hand, with no flex when you squeeze them.

The threads are the critical part, and QT got them right. The cups screw onto the blade base with the same smooth, positive engagement as the original. No cross-threading, no wobble when seated. On both the 600W and 900W bases, the cups lock down firmly and don’t vibrate loose mid-blend.

I ran a standard test — frozen berries, Greek yogurt, spinach, and almond milk — on a 900W base. The blend was consistent with no cavitation or pulsing, and the cup handled the torque without any stress marks. The sealing lids are a genuine upgrade over the OEM flat lids. They snap on with a satisfying click and create a watertight seal. I filled one with water, shook it aggressively, and left it upside down in a bag for two hours. Zero leaks.

What buyers consistently praise

The 4.6-star rating across 229 reviews tracks with my experience. The most repeated compliment is the perfect thread compatibility. One reviewer noted, “I was worried about getting a janky third-party fit, but these thread on exactly like the originals. My 900W doesn’t even know the difference.” Another long-term user mentioned, “I’ve had these for six months and they still look brand new — no clouding, no cracks, and the lids still seal tight.”

The value angle comes up constantly. Buyers consistently point out that two cups plus lids cost less than a single OEM replacement, making this a no-brainer for households that go through multiple smoothies a day.

Where it falls short

The honesty section. First, the “24oz” rating is optimistic. The cup holds 24 ounces to the absolute brim, but the printed MAX line sits at roughly 20 ounces. That’s a real constraint if you’re making large smoothies or protein shakes — you’ll need to leave headroom or risk overflow. Know that going in.

Second, the measurement markings on the side are printed, not molded. After a few trips through the dishwasher, they start to fade. It’s cosmetic, but if you rely on those markings for portion control, it’s an annoyance.

Third — and this is worth repeating — these are cups only. If your blade base is worn out or the gasket is shot, this kit won’t help. You need to verify your existing blade assembly is in good shape before ordering.

Who should buy this

Smoothie daily drivers — if you’re blending every morning and rotating between two cups, this kit gives you a backup without the OEM price tag. Families with multiple Nutribullet users — having extra cups means less washing between uses. Travelers and commuters — the sealing lids are genuinely leak-proof, making these solid for grab-and-go breakfasts.

Skip this if you’re looking for a full pitcher assembly replacement, or if you need the exact OEM carrying ring. Also skip if you only ever make single-serve 8oz portions — the 24oz height might feel oversized for your setup.

FAQ

Q: Will these fit my Nutribullet Pro 900? A: Yes. These fit the standard 600W and 900W models with the classic thread pattern. They won’t fit the Nutribullet Rx or the newer Smart Touch models — those use a different base design.

Q: Can I put these in the dishwasher? A: Yes, top rack is recommended. The cups handle dishwasher heat fine, but the printed markings will fade faster with repeated washing. Hand washing will keep them looking fresher longer.

Q: Do I need to buy new gaskets with these cups? A: No. The cups use your existing blade base and gasket. As long as your current gasket is in good condition — no cracks or warping — you’re good to go.

The Verdict

Buy it if you need reliable, affordable replacements for your Nutribullet 600W or 900W and your existing blade bases are still in good shape. The Tritan build quality matches OEM specs, the threads fit perfectly, and the sealing lids are a practical bonus.

Skip it if you’re expecting a full assembly with blades, or if you need the exact 24oz usable capacity — remember, you’re getting about 20oz of usable blend space.

Rating: 4.6/5 — A solid, honest value that does exactly what it claims. The capacity caveat and fading markings cost it a half-star, but for the price, these are the best replacement cups you’ll find.
