Pack of 12 white 63mm (standard) Spare Jam Jar lids - Ideal for a wide range of jars

Wares of Knutsford

These are 63mm twist off replacement jam jar and glass bottle lids. The vinegar-proof lids are FSA approved, BPA free and suitable for home preserving or commercial use. These twist lids are vinegar and acidic proof making them suitable for pickling and preserves such as chutney as well as jam, marmalade, relish, milk and juice. Create an airtight seal when used with the correct glass jar. The twist closure creates a vacuum seal which is airtight and liquid tight. Preventing leaks and prolonging shelf life. Take care not to over tighten, a quarter of a turn will seal the lid. Check the lid is not cross threaded. Warmed lids work best, they can be heated to a maximum of 60°C. Apply the cap finger tight and then apply pressure for 1/4 of a turn. When filling the jar leave approximately 10mm (5%) space from the rim in order to create the best vacuum and seal. Suitable for the popular 1lb Jam Jar and most standard supermarket sized jam and marmalade jars. To find the correct lid for your jar simply measure across the neck of the glass jar.
