Zojirushi Stopper Gasket

This gasket is designed specifically for model BR128005M-00. To ensure compatibility, check the model number printed on the bottom of your Zojirushi bottle or on the original packaging, as Zojirushi parts are often model-specific.

This is a genuine Zojirushi replacement part. Using original manufacturer components ensures the correct material density and dimensions for a leak-proof seal.

You should replace the gasket if you notice leaks, if the rubber has become brittle or discolored, or if it has absorbed lingering odors that washing cannot remove. Generally, replacing it once a year is good practice for heavy daily users.

No tools are required. You can simply pry out the old gasket with your fingers or a dull, non-sharp object, then press the new one firmly into the groove until it sits flush.

In most cases, yes. A leaking lid is frequently caused by a worn, stretched, or cracked gasket that no longer maintains a tight seal against the bottle rim. Replacing the gasket is the most cost-effective first step to restoring your bottle's performance.
