All-American 921 Pressure Cooker/Canner

Correct. The All-American 921 uses a precision-machined metal-to-metal sealing system. This means you never have to worry about replacing rubber gaskets, which can degrade or leak over time.

While the manufacturer states it is compatible with flat-top stoves, you must exercise caution. Because this unit is heavy-duty cast aluminum and weighs nearly 18 pounds empty, it can scratch or crack delicate glass cooktops, especially when loaded with jars and water.

The 21.5-quart capacity allows you to process up to 18 pint jars or 7 quart jars at a time, depending on the jar style and your stacking configuration.

No, this unit is not dishwasher safe. The heavy-duty cast aluminum construction requires hand washing to maintain the integrity of the metal and the precision-machined seal.

No, this model does not feature an auto-locking lid. It relies on a manual clamping system to secure the lid to the base, which is a standard design for this type of professional-grade canner.

The regulator weight allows you to set the pressure to 5, 10, or 15 psi, covering the standard requirements for most home canning recipes.
