The Preserving Ring is the key to the sealing process and thus preserving success. Fowler's size #2 rings fits bottle sizes 3, 10 and 19. The ring provides an even, airtight seal enabling a vacuum, so that your preserves, may last for years. We strongly advise that the rings be used only once and should be disposed of after opening processed bottles. Re-use of rubber rings will hinder or prevent the sealing process, with potential loss of contents as a result.
Fowlers Preserving Rings are made from natural rubber and are packed in Australia. Comes in a pack of 12 rubber rings.
