Weck rubber rings for perfect sealing of jars

These red natural rubber rings are specifically designed for Weck jars with a diameter of 120 mm. With a pack of 10, you receive durable sealing rings that create the airtight seal essential for successful preserving and long-term food storage.

Ideal for homemade jams, jellies, fermented vegetables, and other preserved foods where secure sealing is necessary.

Reliable seal for your preserving projects

The rubber rings are made from high-quality natural rubber, providing the optimal balance of flexibility and durability. This quality ensures that the rings fit snugly around the jar's rim, preventing air from entering and spoiling the contents. At the same time, the material allows steam to escape during processing—a crucial feature for safe preserving.

The precise fit for 120 mm Weck jars means you can rely on a consistent seal every time.

FAQ

How many times can I reuse the rubber rings?
The rubber rings can be reused multiple times as long as they show no signs of wear, cracks, or deformation. Always inspect them before use to ensure a reliable seal.

How do I know if the seal is correct?
After processing and cooling, the lid should be firmly attached to the jar when the clips are removed. This indicates a proper vacuum. Also, check that the rubber ring sits evenly between the jar and lid without folds.
