A sealing ring, also called a gasket, sits between the lid and the pot of a pressure cooker. It is a replacement part, and the only one that matters is the one made for your model, so brand and size come before everything else.
The six picks below cover three Instant Pot sizes plus Presto, WMF and Fissler parts. Sizes and materials come from each product’s listing page. We have not used these rings ourselves. Fit lists are the sellers’ own, so match your model number before you order.

Sealing Ring FAQ
How often should a ring be replaced?
Follow your maker’s manual. Fissler advises every two to three years for its part.
Can one ring serve sweet and savory food?
Some sellers suggest two rings, one for each, because silicone can hold odors.
