Kilner Fruit Jar

Yes, the two-piece lid system is specifically designed for vacuum sealing, making these jars suitable for preserving jams, jellies, and chutneys using the hot water bath method.

The lids are made of metal and are designed for food preservation, but they can rust if left in standing water or if the coating is scratched. We recommend hand-washing and drying the lids immediately after use to maintain their longevity.

Yes, the glass jars are dishwasher safe. However, we recommend removing the metal lids before placing the jars in the dishwasher to prevent potential corrosion or damage to the seal.

Each jar holds 13.5 ounces, which is a standard size for individual servings of yogurt, overnight oats, or small batches of homemade preserves.

Yes, Kilner sells replacement vacuum seal discs separately. Since the screw bands are reusable, you only need to replace the flat vacuum seal disc after each canning cycle to ensure a proper airtight seal.
