Zojirushi Stopper for SM-NAE

This stopper is specifically designed for the SM-NAE model series. You can verify your bottle's model number, usually found on the bottom of the bottle or printed near the base, to ensure it matches the S87-6B specification.

Genuine Zojirushi parts are engineered to the exact tolerances of your bottle, ensuring the vacuum seal remains intact and the leak-proof performance is maintained. Generic alternatives often lack the precise fit required to prevent spills or heat loss.

Yes. A worn or damaged stopper is often the primary cause of heat or cold loss in vacuum-insulated bottles. Replacing it with a new, tight-fitting stopper restores the bottle's original insulation integrity.

While Zojirushi components are durable, we recommend hand washing the stopper with mild dish soap and a soft brush to preserve the integrity of the silicone seals. High heat from dishwashers can degrade the rubber gaskets over time.

There is no set timeline, but you should inspect the stopper regularly for signs of wear, such as cracking, discoloration, or a loose fit. If you notice leaks or a decrease in temperature retention, it is time for a replacement.
