What the Stopper Cover Fits

The Stopper Cover (White) is designed for Zojirushi models SM-TA36/48/60WA, SM-48KTWA, and TAE48SAWZ. It replaces the outer stopper cover only—it does not include the full stopper set. If your bottle's stopper cover is cracked, worn, or no longer seals properly, this part restores the original fit and function.

Before ordering, confirm your model number is listed in the compatible models. The stopper cover is sold individually, so you will reuse your existing stopper mechanism.

How to Replace the Stopper Cover

Replacing the stopper cover is a straightforward process that takes just a few minutes. Have your new Stopper Cover (White) ready and work over a clean, dry surface.

  1. Remove the old stopper cover: Open the bottle lid and locate the stopper cover on the underside of the cap. Gently pry it off using your fingers or a soft plastic tool. Avoid metal tools that could scratch the plastic.
  2. Clean the stopper area: Wipe the stopper mechanism and surrounding area with a damp cloth to remove any residue. Let it dry completely before installing the new cover.
  3. Attach the new stopper cover: Align the new Stopper Cover (White) with the stopper base. Press firmly around the edges until it snaps into place. Ensure it sits flush and does not wobble.
  4. Test the seal: Close the lid and check that the stopper cover moves freely with the stopper. Fill the bottle with water, invert it, and confirm there are no leaks. If the cover is loose, remove and re-seat it.

Care Tips for Your New Stopper Cover

To extend the life of your stopper cover, hand wash it with mild dish soap and warm water. Avoid abrasive scrubbers and dishwasher cycles, as high heat and harsh detergents can degrade the plastic over time.

Inspect the cover periodically for cracks or stiffness. If the cover becomes difficult to snap on or shows signs of wear, replace it promptly to maintain a leak-free seal.
