Best Oster Blender Glass Jar Replacement: 5 Jars That Fit
Replacing a blender jar sounds simple until you’re standing in your kitchen holding a cracked one. Oster has made blenders for a long time, and the jars changed along the way. So the real job here isn’t picking a jar. It’s matching a jar to the base you already own.
That’s the one thing that separates a good buy from a bad one. Two jars can look almost the same on a screen and still not fit the same machine. The opening width matters. The shape matters, because a cloverleaf jar and a round jar aren’t the same part. The bottom cap matters too, since some jars only lock onto one specific cap number. And the lid is its own question, because plenty of jars arrive without one.
So before you scroll, go look at your blender. Find the model number on the base. Check the shape of the old jar and the width of its mouth. Look at the bottom cap and see if it’s still in good shape, because a worn cap can make a new jar feel loose.
Then read each listing’s own words about what it fits. That’s the whole game with the best Oster blender glass jar replacement.
What you won’t find here is a guess about your model. The listings below say what they fit, and where a listing stays quiet, that silence isn’t a fault. It’s just a gap in the seller’s copy. Your job is to match what’s printed to what’s sitting on your counter.

1. 124461-000 6-Cup Round Glass Blender Jar
Best for: Oster and Osterizer owners who need a plain round jar
This is the straightforward one. Univen lists it as a 6-cup round glass jar with a 5″ opening, made to fit Oster and Osterizer blenders. If your old jar was round and your base is an Osterizer, this is the shape you’re replacing. The 5″ opening is the number that matters most here, because it decides whether your existing lid still seats.
What owning it’s like comes down to one word: lid. The listing says plainly that no lid is included. So if your old lid survived the crack, you’re set. If it didn’t, you’re buying a jar and then hunting a lid separately, which is a second order and a second wait. That’s the trade-off, and it’s worth knowing before you click.
The jar itself is glass, 6 cups, round. Nothing on the listing promises more than that, and nothing needs to.
| What it gives you | What you accept |
|---|---|
| 6-cup round glass jar | No lid in the box |
| 5″ opening | Fits Oster and Osterizer only |
| Fits Oster and Osterizer bases | You supply or replace the lid |
2. Univen Cloverleaf Glass Jar
Best for: Blenders that originally came with a cloverleaf jar
Cloverleaf is a shape, not a style choice. If your Oster blender came with a cloverleaf jar, a round jar won’t sit right on it, and this is the part you want. Univen lists it as fitting Oster blenders that use a glass cloverleaf shaped jar. That’s a narrow fit on purpose.
The listing also names a lid: it can be used with the OS-LIDCLBK lid. That’s useful, because it tells you exactly which lid to look for if yours is gone. It doesn’t say a lid is in the box, and the listing states it doesn’t include one. So plan for the lid as a separate item.
This isn’t the jar for someone who isn’t sure what shape their old jar was. If you’re guessing, measure first. A cloverleaf jar and a round jar are different shapes, and the listings treat them as such.
What goes smoothly:
- Matches the cloverleaf shape your blender was built around
- The listing names a specific lid that works with it
- Glass jar, same material as the original
What you have to accept:
- No lid included
- Only fits blenders that use a cloverleaf jar
3. Anbige Replacement parts 6-Cups Glass Jar
Best for: Buyers who want the whole assembly in one box
This is the most complete package of the group. Anbige lists a 6-cup glass jar, a lid, a 6-point blade, a gasket, and a bottom cap, with the cap listed as replacement part 004902-003-NP0. If your old jar, blade, and cap are all tired, this replaces the lot in one order.
The model list is the other reason to look here. The listing names a long run of compatible blenders, from 006803 and 006811 series through BLSTCC, BLSTFG, BLSTMG, BLSTMP, and BCCG08 models. That’s a wide net. Read it against your own model number rather than assuming.
The trade-off is that a kit means parts you may not need. If only your jar cracked and your blade and cap are fine, you’re storing spares. That’s not a problem, just a fact of buying the bundle.
Snapshot:
- Glass jar plus lid, blade, gasket, and bottom cap
- Bottom cap listed as part 004902-003-NP0
- Long list of named compatible Oster models
- One order covers the full assembly
- Spare parts if your blade and cap are still good
- Check your model number against the list before buying
4. Joyparts Replacement Parts Glass Jar with lid
Best for: Oster Pro 1200 owners replacing just the jar
If you own an Oster Pro 1200, this listing is aimed straight at you. Joyparts names three compatible models: BLSTMB-CBG, BLSTMB-CBF, and BLSTMB-BBG. It’s a glass jar sized for everyday blending, and the lid comes with it. That’s the whole package, and for a lot of buyers that’s exactly enough.
The narrow fit is the point. This isn’t a jar for a classic Osterizer or a Versa. It’s for the Pro 1200 line, and the listing says. If your model number isn’t one of those three, keep reading down the list.
Check your model number before you order. It’s on the rating label under the base, and it’s the only thing that decides whether this jar works for you. BLSTMB-CBG, BLSTMB-CBF, BLSTMB-BBG — those three, and nothing else. A jar that doesn’t match won’t seat on the base, and you’ll be paying return shipping to find that out.
Who it fits: Pro 1200 owners who cracked the jar and still have a working blade and cap. The lid being included means you don’t chase a second part.
Who should pass: Anyone whose base isn’t a BLSTMB model. And anyone whose bottom cap is worn, since this listing doesn’t include one.
If you’re in the first group, the order is simple: one jar, one lid, nothing else to buy. If you’re in the second, the listing doesn’t mention a bottom cap, so check your own before ordering.
5. Anbige Replacement Parts 6-Cup Glass jar with Lid
Best for: Pro 1200 owners who want a dishwasher-safe jar
Same three Pro 1200 models as the pick above: BLSTMB-CBG, BLSTMB-CBF, BLSTMB-BBG. So the fit question is settled the same way. What’s different is the detail. This listing says the jar is dishwasher safe, which matters if you’d rather not hand wash glass every time you make a smoothie.
It also names a specific bottom cap: part 179854-000-000, and says the jar only works with that cap. That’s a hard requirement, not a suggestion. Check your cap number before you order.
One thing to read carefully: the listing’s title says 6-cup, and the package line says 5-cup glass jar with lid. Both appear in the same listing. If capacity is the deciding factor for you, that’s worth resolving before you buy.
What goes smoothly:
- Fits the three named Pro 1200 models
- Lid included
- Dishwasher safe per the listing
- Clear glass jar
What you have to accept:
- Only works with bottom cap 179854-000-000
- Title and package line disagree on capacity
Also Worth Considering
The Joyparts 6-Cup Replacement parts Glass is a glass jar that comes with a blade, listed as compatible with Oster blenders. The listing’s title is the only thing to go on here, so match your model to the Oster fit it claims.
The Kuntorie Cup Blender Glass is a glass jar with a blade, and its title is unusually clear about one thing: it’s for Aspas Para Licuadora Oster Osterizer Classic Series, and it doesn’t fit Pro, Master, or Versa models. That’s a helpful line. If you own a Classic Series Osterizer, this one is worth a look. If you own a Pro 1200, it’s not for you.
The Decision Filter
First, determine the shape of the jar you’re replacing: round or cloverleaf. That single answer cuts this list in half, because the cloverleaf jar only fits blenders built for it, and a round jar won’t take its place.
Then ask whether your base is a Pro 1200 or something older. The two Pro 1200 jars only fit three named models. Everything else here is aimed at the wider Oster and Osterizer range.
One more check before you commit: the opening of the blender base. On at least one jar here, that opening has to measure 3 3/8 inches. If your base opening is bigger, that jar won’t fit, no matter how right the rest of it looks.
Most people miss this: the bottom cap. It’s the piece at the base of the jar, and some jars only lock onto one specific cap number. Check it before you order, not after.
If you’re still holding two options after those questions, pick the one that includes the lid you need. Some jars here ship with a lid, some don’t, and one cloverleaf jar names the lid it takes.
Then look at what else is in the box. Some listings are the jar alone. Others add the blade, the gasket and the bottom cap.
The Quick Checklist
- Do you know your blender’s exact model number, not just the brand?
- Is your old jar round or cloverleaf shaped?
- Do you still have a lid that fits, or do you need one included?
- Is your bottom cap in good shape and the right part number?
- Will anyone else in the house use it and need it to be simple?
- If it arrives and doesn’t fit, can you return it easily?
Three Regrets Worth Avoiding
Regret #1: Buying a jar without checking the lid. Several jars here ship without one, and that’s stated plainly in their listings. The fix is simple: read the package line before you order, and if no lid is listed, plan to buy one.
Regret #2: Ignoring the bottom cap. One jar here only works with cap part 179854-000-000, and another lists its cap as part 004902-003-NP0. A cap that’s the wrong number is worth checking against the listing before you order. The fix: take your cap off, read the number on it, and match it to the listing.
Regret #3: Assuming every Oster jar fits every Oster blender. The Pro 1200 jars fit three named models. The Kuntorie jar says outright that it doesn’t fit Pro, Master, or Versa. Oster has made a lot of blenders over the years, and the jars aren’t interchangeable across all of them. The fix: find your model number on the base and match it to the listing’s own words.
If You Want This, Look for That
Here’s the short version of what to hunt for, and what to walk past.
| If you want… | Look for | Avoid |
|---|---|---|
| A jar that fits your Osterizer | Round jar, 5″ opening | Cloverleaf shape |
| To keep your existing lid | Jar listings that don’t include one | Assuming a lid ships |
| Everything in one order | Jar, lid, blade, gasket, cap | Buying parts one at a time |
| A Pro 1200 replacement | Your exact BLSTMB model number | Classic Osterizer jars |
| Easy cleanup | Dishwasher safe in the listing | Hand-wash-only habits |
| A cloverleaf blender | Cloverleaf jar and OS-LIDCLBK lid | Round jars |
Two rows in that table decide most purchases, so slow down on them.
The first is the model split. Joyparts and Kuntorie both say plainly that their jars don’t fit Pro, Master or Versa models. The Anbige and Joyparts Pro 1200 jars name the BLSTMB models they do fit. If your blender is a Pro 1200, a jar built for a Classic Series machine is the wrong buy, and no lid or blade will rescue it.
The second is the opening. Kuntorie gives you a number to check: the opening of your blender base must be 3 3/8″. If yours is bigger, that jar won’t fit. Measure before you order rather than after.
Then count what arrives. Some listings ship a jar alone. Others add a lid, a blade, a gasket and a bottom cap. One Anbige jar works only with bottom cap 179854-000-000, so a jar without that cap isn’t a swap you can make.
None of these jars is an original part. They’re aftermarket replacements, which is why the fit lists matter more than the brand name on the box.
Frequently Asked Questions
Will a round jar fit a blender that came with a cloverleaf jar?
No. These are two different shapes, and the listings treat them as such. The Univen Cloverleaf jar is listed for Oster blenders that use a glass cloverleaf shaped jar, while the round Univen jar has a 5″ round opening. If you’re not sure which you have, look at the mouth of your old jar from above.
How do I find my Oster blender’s model number?
Look on the bottom of the base, or on the back near the cord. It’s usually a string like 006803-000-NP0 or BLSTMB-CBG. Write it down exactly, including the letters and dashes. Then read it against the compatible model list in the listing. The Anbige jar names a long run of models, and the two Pro 1200 jars name three each. An exact match beats a guess every time.
What if my jar arrives without a lid and I need one?
Two of the jars here state clearly that no lid is included. If that’s a problem, the Anbige jar and both Pro 1200 jars list a lid in the package. For the cloverleaf jar, the listing names the OS-LIDCLBK lid as the one that works with it, so that’s the part to search for. Buying the lid at the same time as the jar saves you a second wait.
Can I put the glass jar in the dishwasher?
One listing here says yes: the Anbige Pro 1200 jar is listed as dishwasher safe. The others don’t state it either way. If dishwasher cleaning matters to you, that’s the listing to check first.
Why does the bottom cap matter so much?
Because some jars only work with one specific cap. The Anbige Pro 1200 jar states it only works with part 179854-000-000. The Anbige 6-Cup jar lists its cap as part 004902-003-NP0. If your cap is the wrong number or worn out, the jar may not seat properly. Take your cap off, read the number molded into it, and match it before ordering.
What’s the difference between the two Pro 1200 jars?
Both fit the same three models: BLSTMB-CBG, BLSTMB-CBF, and BLSTMB-BBG. Both include a lid. The differences are in the details. One is listed as dishwasher safe and names a required bottom cap number. The other is a simpler jar-and-lid package. One listing also shows both 6-cup and 5-cup in its own text, so if capacity is your deciding factor, read that listing carefully.
Do I need to replace the blade and gasket too?
Only if they’re worn. The Anbige 6-Cup jar includes a 6-point blade, a gasket, and a bottom cap along with the jar and lid, so it covers everything in one order. The other jars here are jar-only or jar-and-lid. If your blade still cuts and your gasket still seals, you don’t need them. If your smoothies come out gritty or the base leaks, that’s your sign.
Closing
When two picks still look equal, use this tie-break: count how many parts come in the box that you actually need. If your blade and cap are fine, the jar-only option wins. If your blade is dull and your cap is cracked, the kit covers those parts in one order.
Then do one thing before you buy. Find your blender’s model number on the base and read it against the listing’s compatible model list. That takes only a moment and settles most of the doubt.
If your model isn’t named, look at the jar shape and the opening instead, and match those. One jar states its opening is 5 inches. Another says the opening of your base must be 3 3/8 inches, and that a bigger opening won’t fit. Measure yours before you order.
And if your old lid survived, keep it. A lid you already own is one less thing to chase. Some jars ship with a lid, some do not, and at least one jar is built to take a specific lid sold on its own.
