Keep your Zojirushi thermal mug working like new with this complete set of replacement lid parts. Designed specifically for SM-SA and SM-KA models, this kit includes the bouncing lid seal ring, plug gasket, and washer to stop leaks and restore your mug's original performance. Made from soft, food-grade silicone, these parts create a tight seal that keeps your drink hot or cold for hours.

Over time, the rubber seals on your favorite travel mug can wear out, crack, or lose their shape. That leads to annoying drips, spills, and reduced insulation. Instead of buying a whole new mug, you can simply swap out the old gaskets with this affordable replacement set. It is a quick fix that extends the life of your Zojirushi mug and saves you money.

Each component is molded to match the original factory dimensions for a precise fit.

Whether you use your mug for coffee, tea, or hot water, these seals will keep everything securely inside until you are ready to drink.

Installing the parts is straightforward and takes just a few minutes. You do not need any special tools or skills. Just remove the old seals and press the new ones into place. This simple maintenance step can make a big difference in how your mug performs every day.

Usage Scenario

Mark takes his Zojirushi thermal mug to the office every morning. After a year of daily use, he noticed coffee was leaking from the lid onto his desk. The seal ring had worn flat and no longer pressed tightly against the cup. He ordered this replacement set, popped out the old gasket, and snapped the new one in place. The next morning, his mug was leak-free and kept his coffee hot until lunch. He saved himself the cost of a new mug and avoided a messy cleanup.

Buying a brand new Zojirushi thermal mug can cost three to four times more than this simple repair kit.
