Zojirushi Lid Cover Gasket

This gasket is specifically engineered for the SM-YAE series. Always check the model number printed on the bottom of your container or the original packaging to ensure a precise fit, as Zojirushi gaskets are not universal.

Over time, silicone gaskets lose their elasticity and can develop micro-tears or absorb odors that cleaning cannot remove. Replacing the gasket restores the original, airtight seal, which is essential for preventing leaks and maintaining temperature retention.

Not at all. Replacing the gasket is a straightforward process that requires no tools. Simply remove the old, worn-out seal from the lid groove and press the new one firmly into place, ensuring it sits flush all the way around.

While there is no fixed timeline, you should replace the gasket if you notice any visible cracking, hardening, or if your container begins to leak. For heavy daily users, replacing it once a year is a good practice to keep your drinkware performing like new.
