Weck Rubber Ring RR120 pack of 10

Weck rubber rings for a perfect seal on preserving jars

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

Ideal for homemade jam, marmalade, fermented vegetables, and other preserved foods where a secure seal is essential.

Reliable sealing for your preserving projects

The rubber rings are made from premium natural rubber that provides the optimal balance between flexibility and durability. This quality ensures the rings close tightly around the rim of the jar, preventing air from entering and spoiling the contents. At the same time, the material allows steam to escape during heat treatment – a crucial function for safe preserving.

Extended shelf life for your homemade delicacies

With these specially designed rubber rings, you can preserve the flavour and nutrients in your homemade products for longer. The precise fit for 120 mm Weck jars means you can rely on a consistent seal every time. This not only provides better food safety but also reduces food waste and allows you to enjoy seasonal produce all year round.

Frequently asked questions

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 preserving and cooling, the lid should remain firmly on the jar when the clips are removed. This indicates a correct vacuum. Also check that the rubber ring sits evenly between the jar and lid without any folds.
