“I am sure the sealing ring will be fine when ordered for the correct pressure cooker. However my pressure cooker model was not obvious so I went by measuring mine which though it measured as stated did not fit. It would be reassuring if my model number was listed in the ‘suitable for..’ section. I have now reordered and hope for a refund. I would be happier with a more detailed website. Pressure cookers last a long time and older ones should continue to be listed, the model number did not even show up in the search, only the recommended ring model.”
