Learn how to replace the upper stopper on your Zojirushi SH-FB19 thermal carafe with this step-by-step guide. Fix leaks and restore function with a genuine replacement part.

Quick answer

Replacing the upper stopper on your Zojirushi SH-FB19 thermal carafe is a straightforward fix that takes just a few minutes. The black upper stopper (part number 7-SHF-P021) is available from the Zojirushi Online Store and restores a tight seal when the original stopper wears out.

When to replace the upper stopper

The upper stopper on the SH-FB19 is the black plastic piece that sits inside the lid and presses against the carafe opening. Over time, the rubber seal can harden or crack, causing leaks or a poor pour. If you notice drips after closing the carafe or the stopper feels loose, it is time for a replacement.

Using a genuine Zojirushi part ensures the fit and seal are correct. The Upper Stopper (Black) for SH-FB19 is specifically designed for this model, so aftermarket parts may not seal properly.

What you need

You will need the replacement upper stopper (part number 7-SHF-P021) and a small flat-head screwdriver or a plastic pry tool. No special skills are required, but work over a towel or sink in case any small parts fall out.

Step-by-step replacement

Remove the lid assembly: Open the carafe lid fully. Press the release button on the lid handle to separate the lid assembly from the carafe body. Set the carafe aside. Common mistake: forcing the lid off without pressing the release button can break the hinge.
Remove the old upper stopper: Turn the lid assembly over. Locate the black upper stopper — it is held in place by a small retaining ring or clip. Use a flat-head screwdriver or pry tool to gently lift the retaining ring out of its groove. Slide the old stopper off the pivot pin. Checkpoint: note the orientation of the stopper — the flat side faces the carafe opening.
Install the new upper stopper: Slide the new black upper stopper onto the pivot pin in the same orientation as the old one. Press the retaining ring back into its groove until it snaps securely. Give the stopper a gentle tug to confirm it is locked in place. Common mistake: not fully seating the retaining ring can cause the stopper to pop off during use.
Reattach the lid assembly: Align the lid assembly with the carafe body and press down until you hear a click. Close and open the lid a few times to ensure the stopper moves freely and seals against the opening. Checkpoint: fill the carafe with water, close it, and tilt it over a sink to test for leaks before regular use.
