Zojirushi Cap Packing

This part is designed for specific Zojirushi models. You should verify that your bottle matches the model number BB412012M-00, which is typically found on the bottom of the container or in your original user manual.

Genuine parts are manufactured to the exact specifications of your original bottle. Using authentic components ensures the seal is airtight and leak-proof, whereas generic alternatives often fail to provide the precise fit required for Zojirushi's vacuum insulation technology.

You should replace the packing if you notice it has become brittle, discolored, or if the bottle begins to leak. Even with regular cleaning, silicone seals naturally degrade over time and lose their elasticity.

Yes, replacing the seal can often resolve issues with lingering odors. Over time, silicone can absorb the scent of beverages like coffee or tea, and a fresh seal is a quick way to restore your bottle to a neutral state.
