O-Ring Gaskets 🫧—the tiny fix that saves blender days ✨
If your Oster or Osterizer blender has ever felt a little “leaky” or messy around the jar base, a sealing gasket is often the culprit—and this set is made to help you get back to smoother blending.
Quick heads-up: compatibility depends on your exact blender model, so it’s smart to double-check before ordering.
What this product is
This is a 5-pack of rubber sealing O-ring gaskets designed as replacement parts for compatible Oster and Osterizer blenders. Honestly, these are the kind of small components you don’t think about until you notice drips, dribbles, or overflow during blending.
Why it matters
The biggest appeal is the sealing. These gaskets are made from elastic rubber (non-toxic, odorless, and food-safe as described) and are intended to fit snugly to help prevent liquid leakage and food overflow during blending. They’re also meant to be simple to swap—remove the jar base cap and ice blade, replace the old gasket, and you’re back in business.
Quick compatibility reality check
This set is compatible with for Oster and Osterizer blenders, but it’s specifically noted as not compatible with Oster Pro 1200 and In2uitive models. If you’re unsure, check your blender’s model and size before purchase for the best fit.
Size you should verify
The inside diameter is approximately 1.97 in / 5 cm, and the outside diameter is approximately 2.6 in / 6.6 cm. Measuring (or comparing) before you buy can save you a lot of “why won’t this seat right?” moments.

Why This Product Exists
This is basically for people who love their blender… but hate when a small part turns it into a kitchen cleanup project. At some point, gaskets can wear down or deform, and rather than replacing the whole blender, a replacement seal can be the practical move.
It’s also a nice “just in case” option—having extra gaskets around means you’re not stuck waiting if you notice a seal issue mid-week.
Best Fit For
You have a compatible Oster/Osterizer blender
You’re looking for a replacement gasket to help with sealing around the jar base during blending.
You’re trying to avoid replacing the whole unit
You’d rather swap a gasket than deal with the hassle and expense of buying a new blender.
Not ideal if: your blender is one of the models listed as not compatible (Oster Pro 1200 or In2uitive), or if the gasket size doesn’t match what your blender needs.
Final Verdict
Honestly, this is a simple, practical replacement part: rubber O-ring gaskets intended to help restore a tighter seal for compatible Oster and Osterizer blender setups. If you’ve been dealing with leakage or overflow, this kind of gasket swap is a pretty reasonable first step—just make sure your model and gasket size match before you hit “buy.”
