All American 1930 Pressure Cooker/Canner 921 — 21.5 qt, Metal-to-Metal Seal — Made in Manitowoc, Wisconsin by Wisconsin Aluminum Foundry under the All American brand since 1930. Heavy-gauge cast aluminum body with the exclusive metal-to-metal sealing system — no rubber gasket to wear out, no consumables to replace, just precision-machined surfaces and a wing-nut clamp.
Wisconsin Aluminum Foundry has manufactured All American pressure cookers and canners in Manitowoc, WI since 1930. Each canner is sand-cast from heavy-gauge aluminum at the same Wisconsin foundry, machined for a precise seal, and assembled by American workers. The metal-to-metal seal is the differentiator — most other canners rely on a rubber gasket that warps and needs replacement.
For home canners putting up summer produce, prepper households storing shelf-stable jars, and commercial kitchens running daily pressure-cooking. Built to last generations — buy once, hand it down.
