⚡ At a Glance
- • Sealing Quality: Soft silicone forms a snug lip inside lids to reduce air ingress and retain freshness
- • Best for: Home cooks, jam makers and anyone reusing Kilner or Mason-style glass jars
- • Not ideal for: Unusually sized or bespoke jar mouths that fall outside most standard dimensions
Pack contains 12 food-grade silicone gaskets designed to fit most standard glass jars. Stretchable, elastic material sits inside jar lids to create a close, reliable seal.
Restored airtight storage - thanks to food-grade silicone gaskets
Food-grade silicone is soft, flexible and slightly stretchable, allowing rings to be expanded then set inside a lid where they contract to form a tight seal. Material resists deformation in cold storage according to the description.
A snug gasket helps preserves and keeps odours contained, extending the usable life of leftovers and homemade preserves.
Quick, tool-free replacement - with stretch-fit installation
Rings are designed to be gently stretched to expand, then positioned inside the lid so the silicone wraps and fixes around the inner rim. No tools or specialist skills are required for installation.
Old or brittle jar gaskets can be replaced in seconds, making jars usable again without buying new lids or containers.
Durable everyday use - with flexible, resilient construction
Silicone composition is described as strong, soft and elastic, suitable for repeated stretching and use in a refrigerator without noticeable deformation. The pack supplies multiple spare rings for rotating replacements.
Regular kitchen use and cold storage are supported, so seals last through repeated cycles and reduce the need for frequent replacements.
