Fowler Vacola Seals No. 3 (12)
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. Rings will naturally deteriorate and need regular replacement. Always inspect rings for hair line cracks or loss of elasticity. Re-use of unsuitable rubber rings may 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.
