The Fowlers Vacola Preserving Ring is the key to the sealing process and thus preserving success. The Preserving Rings are made from natural rubber and provide an even, airtight seal enabling a vacuum seal, so that your preserves, may last for years.

Tip: 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.
