Ball Canning Lids

No, these lids are designed for single-use only. The sealing compound on the underside of the lid is intended to create a one-time vacuum seal, so you should use a fresh lid for every canning project to ensure food safety.

These lids are specifically designed for regular-mouth jars, which typically have a 2.625-inch diameter opening. They will not fit wide-mouth jars, so be sure to check your jar size before purchasing.

Yes, these lids are freezer safe. They provide a reliable, airtight seal that helps prevent freezer burn when storing preserved goods or other food items in the freezer.

Yes, these lids are constructed with BPA-free materials. You can use them for home food preservation with the confidence that no harmful chemicals will leach into your stored food.

Once the jar has cooled completely, the center of the lid should be slightly concave and remain firm when pressed. If the lid flexes or pops when you press the center, a proper vacuum seal was not achieved.
