The ALL-AMERICAN® Pressure Canner/Cooker features an exclusive, precision machined "metal-to-metal" sealing system. Positive action clamping locks align the cover to the base, forming a steam-tight seal. Since the seal does not use a gasket, the cover can be easily opened and closed. Use it to can fish, meat, vegetables and fruits – it's the only method the USDA recommends for low-acid foods. It features a precision machined regulator weight for accurate pressure control and an easy-to-read, 8.5 x 5.5″ Instruction and Recipe Book. It is suitable for gas, electric, or flat top stoves but is not recommended for glass-top stoves. Additional features include a sturdy phenolic top handle; smooth, easy-to-clean satin finish; easy on-off cover; positive action clamping wing nuts permit easy opening and closing; double thickness edges for additional protection on points of heaviest wear; and automatic overpressure release. With an inside diameter of 15-3/8" H x 12-1/4", it has a regular mason jar capacity of 19 pint or 7 quart jars.
