What chuck size do I need for my can sealer?

The following chart is a comparison list of can sealer chuck sizes and the food can sizes that each associated chuck will seal:

The chuck size that you will need for your can sealer depends on the can size diameter that you are wanting to seal.
The chuck is a disk-type part of the can sealer / seamer that holds the lid in place on top of the can during the seaming process.
All can linings / coatings are food grade unless specifically specified otherwise – call for details.

Note that it is important that the chuck size diameter correctly matches the can size diameter in order for the seaming process to be successful.
