5Pcs Rubber Gaskets 😊🧼
If your blender starts acting a little… leaky… this is the kind of small fix that can feel weirdly satisfying. Swap the seal ring, get back to smoother blending.
What this replacement gasket set is for
This 5-pack rubber gasket replacement is designed to fit certain Nutri Ninja / Ninja Pro Extractor blade assemblies so the seal between the blade and the cup can stay snug.
Honestly, gaskets are one of those “small parts, big difference” things—when they’re worn or not seated right, you’ll notice it.
The seal ring set is intended for compatible 3.94 in diameter Ninja blades and is made from food-grade rubber (per the listing).
It also includes a hook, and the install style is pretty straightforward: remove the old gasket, pre-press the new one so it sits correctly, then push it down as far as possible for a tighter fit.
- Seal diameter: 3.94 in (10 cm); height: 0.4 in (1 cm), based on the product details.
- Designed for compatible Ninja blades that are 3.94 in in diameter.
- Only fits 18 / 24 / 32 oz blender cups; not for 16 oz blender cups.
- Compatible with listed models and blade assemblies in the provided compatibility list.
- Some “-70” variants are noted as not compatible (for example, BL450-70 and similar).
- For the most accurate match, double-check your specific model number against the compatibility list in the listing.
- Made of food-grade rubber (per the listing), intended for strong sealing and long-term use.
- Each pack includes 5 rings and a hook.
- Grooves are different on each side of the ring: face UP for grooves and bumps; face DOWN for the concave side.
- After replacing, push the gasket down as far as possible so it sits tightly against the blade.
- Before replacement, remove the old gasket and pre-press the new washer to help proper installation.
At some point, most blender owners run into the same annoying reality: seals wear out, get mis-seated, or just don’t hold like they used to.
This gasket set exists for people who want to keep using their blender without treating every smoothie session like a science experiment.
It’s basically a practical “maintenance mode” option—designed to help restore the sealing connection for compatible cups and blade assemblies.
- People with compatible Nutri Ninja / Ninja Pro Extractor blade assemblies who need replacement seal rings.
- Anyone using 18 / 24 / 32 oz blender cups (not 16 oz cups, per the listing).
- DIY-minded blender owners who are comfortable doing a gasket swap and following the “grooves up / concave down” install direction.
If you’re unsure about compatibility, check your exact model/blade assembly number before ordering.
This is a simple, replacement-focused gasket set for specific 3.94 in blade assemblies and compatible cup sizes.
If your blender’s seal isn’t sitting right anymore, a fresh gasket is a sensible thing to try—just make sure you match the exact cup size and the specific “-30” style compatibility notes from the listing.
No pressure—just verify compatibility with your specific model/cup setup first.
