Weck Replacement Seals

Keeping your Weck jars completely airtight is vital if you want to make sure your home-made produce lasts. There's nothing worse than opening that jar of jam months later to find it's inedible. Weck recommends you use new rubber seals each time to ensure a complete seal (full instructions are sent out with your jars).

Please note these seals are made from natural Indian rubber so they must not come into contact with oil based content or the rubber will expand causing the jar to no longer be airtight.
