Reliable seals are key to safe, long-term storage of homemade preserves. This set of 20 silicone rings for WECK jars provides a tight, airtight seal that protects contents from air and moisture, thereby extending the shelf life of your goods. The durable silicone handles high temperatures excellently, so the rings can be used confidently during pasteurization.
Thanks to standardized dimensions — outer diameter 11 cm and inner diameter 9.2 cm — the seals are compatible with common WECK jars. The red color helps with clear sorting and quick replacement during regular maintenance, which we recommend to maintain maximum sealing performance and food safety.
