Official Presto pressure canner parts

Common replacement parts for Presto pressure canners

• Pressure gauge. The pressure gauge measures pressure in pounds per square inch, or PSI. The pointer moves around the dial indicating the pressure within the unit. Pressure can be controlled and maintained by adjusting the heat setting on your stove.
• Pressure regulator. The pressure regulator acts as a safety device to prevent pressure in excess of 15 pounds from building in the pressure canner.
• Vent pipe. The vent pipe is the primary pressure relief valve and will release pressure in excess of 15 pounds. The pressure regulator sits loosely on the vent pipe.
• Seal ring. The seal ring fits into the canner cover and forms a pressure-tight seal between the cover and body during canning and cooking.

Safety precautions to follow when using your Presto pressure canner

• Read the owner's manual for your pressure canner before using the appliance. Follow all safety and use guidelines in the manual to prevent injuries.
• Always check the vent pipe before use. Hold the cover up to a light and look through vent pipe to be certain it is clear.
• Check the air vent/cover lock to make sure it moves freely before use.
• Don't fill the pressure canner over ⅔ full when pressure cooking. For soup, grains, and dry beans and peas which expand during cooking, don't fill the canner over ½ full. Overfilling may cause a risk of blocking the vent pipe and developing excess pressure.
