If you have been enjoying the benefits and ease of pressure cooking with your Kuhn Rikon Duromatic pressure cooker but need to replace the rubber seal (gasket), all you need to do is check the size of the pan by looking on the bottom for the pan measurement or check in your manual. Using replacement parts made by a different manufacturer can detrimentally affect the safety of your pressure cooker. To keep your gasket in tip top condition remove the rubber gasket from the lid each time you use this piece of kitchen equipment, rinse out and wash the rubber gasket and the lid, especially its exposed edge. Never wash in a dishwasher and when storing, place the inverted lid on the pan so that the rubber gasket inside the lid remains unstressed and free of deformation. The spare gasket is easily fitted and you can continue to cook in a fraction of the time, conserving vitamins and flavours, whilst saving up to 70% of the energy used in conventional cooking.
