Review on 🔒 Presto 09906 Pressure Cooker Sealing Ring/Automatic Air Vent Pack: Efficient Seal for 4 & 6 Quart Cookers by Monica Williams

I'm glad National Presto Industries (makers of Presto cookers) are still supporting their older products by providing these replacement parts. I was able to rejuvenate an old pressure cooker (with a copper bowl covered in stainless steel). Now it works like new. The pad fitted perfectly. I'm glad I didn't have to buy an inferior new product or an expensive aluminum model. If you're not sure which seal kit you need, go to the Parts and Service page of gopresto.com to find the right product. You will need the model number of your old oven. I found it on my 804 at the bottom of the bowl. The manufacturer recommends replacing the O-ring and vent at the same time.
