Introduction
A sealing ring with a tab or notch is an improved design that makes installation and handling easier, not a defect.


Description
Some customers notice that a replacement Instant Pot sealing ring has a small tab, notch, or special molded shape and assume it may be a production error. In fact, this is an intentional design improvement.

The added shape is made to help with easier installation, removal, and everyday handling of the sealing ring. Users have consistently confirmed that this feature makes the ring easier to fit into the lid, easier to remove for cleaning, and easier to position correctly.

Although the ring may look different from an older original version, this design difference does not affect compatibility, sealing performance, or safe use. The sealing function still comes from the full silicone ring sitting evenly and correctly in the lid. The molded tab or notch is simply an added practical feature that improves handling.

Because of this updated design, the ring may not look exactly the same as the original ring supplied with the pressure cooker, but this does not mean there is any problem with the product. The shape is intentional and part of an improved user-friendly design.

What to do

  1. Check that the sealing ring matches the correct size for the Instant Pot model.
  2. Install the ring evenly under the retaining wire inside the lid.
  3. Make sure the ring sits flat all the way around and is not twisted.
  4. Use the molded tab or notch as a helpful point for fitting, adjusting, or removing the ring during cleaning.
  5. If the ring fits securely and the cooker reaches pressure normally, the ring is working as intended.
  6. If the ring cannot be fitted correctly or the appliance does not seal properly, contact an authorized service center for further inspection (please include pictures of the problem).

Conclusion
A sealing ring with a tab, notch, or special molded shape is not a production error. It is an improved design feature that makes installation and handling easier, while maintaining normal compatibility, sealing performance, and safe use.
