What kind of pressure canner do you use? Ours is an All American, holds 7 qts. or 16 pts. and is steel on steel, no rubber gasket. We sure like it and have never had a minutes trouble from it in 25 years.
I have the same one, from the sounds of it. Model 915. My mom gave it to me several years ago when she quit canning. I can't imagine any other brand being any better. It's a quality canner! I wish I had another one just like it. There are times I could use two.
