The Preserving Ring is the key to the sealing process and thus preserving success.
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.
