Presto 3-4 Quart Pressure Cooker Sealing Ring & Automatic Air Vent Replacement Pack (09909) - Perfect for Safe & Efficient Cooking at Home

This seal is a perfect fit for my Presto 4 quart stove top pressure cooker. To install properly, you must seat the rubber seal completely into the groove and firmly hold it in place as you continue around the lid pushing the seal towards where you are holding it in place. Make sure the groove is totally clean before starting. Yes, it is a little tricky to accomplish, but is doable with patience - and some strength in your hands and fingers! This cooker is like new with the new seal and steam plug and should another 50 years.
