Over time as the canner lid is handled, bumped, or just used, the calibration of a dial gauge can become inaccurate. Even gauges on new canners and replacement gauges need tested before use. So bring it in for testing.

It is also recommend that you convert your single weight to the 3 part weight for Presto canners. For All American it is a round weight that replaces the vent pipe with a petcock. It has 3 holes for 5lb, 10lb and 15lb pressure. Weights never need to be calibrated, the gauge becomes an indicator when you can safely remove the lid. Please contact the manufacturer below to ensure you order the correct one.


  • Please wear a mask and maintain physical distancing.
  • The gauge will be tested using calibrated equipment, and the entire process should take no longer than 5-10 minutes per gauge.
  • Contact Denise Ashley with questions or accommodations.
