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

3 years 5 months. I couldn't seal it anymore so I replaced it with the same one. I use this thing about twice a month. 3 years and 2 months later it just started leaking a little, turn off the heat, release the pressure and quickly rub the inside of the rubber seal with some vegetable oil on a paper towel and it does. It's a bit disappointing that it only lasted 3 years. Also, I never cleaned properly behind the gasket and got some rust on the back, I worked and worked with a comet and a bartenders friend to remove all the rust and smooth out the stain. (1/2"x1/4"") and that's it. Now I remove the gasket when washing the lid and dry everything before putting it away. Works perfect. It comes crumpled in a small box and looks damaged - it's not.
