Ours in Oregon even tested canners at one time. The seal do go bad after some usage. It's a Presto Pressure Cooker, holds 6 quarts. Not officially a canner, but I used to have a pressure cooker that I used successfully for canning, for years. I do not have instructions for that type of canner, and I do not think I would use that type of cooker for canning.
Different food require different pressures and times.
