Weck Rubber Ring RR100 – pack of 10

Weck rubber rings for a secure seal on preserving jars

These red Weck rubber rings with a diameter of 100 mm are made from high-quality natural rubber. They are specifically designed for Weck RR100 jars and ensure an airtight seal that is essential for successful preserving and long-term storage of food.

Ideal for home-made jam, marmalade, bottled vegetables, soups, and other preserved foods.

Natural rubber for an optimal seal

The rubber rings are made from premium natural rubber, which provides excellent elasticity and durability. This quality is crucial, as the rings must create a completely airtight seal that prevents air from entering the jar after preserving. At the same time, they allow steam to escape during the heating process, which is essential for achieving the vacuum that keeps food fresh.

Long-lasting preservation

With these rubber rings, you can preserve the fresh flavours of the season all year round. They create the hermetic seal needed to significantly extend the shelf life of your home-made preserves. Each pack contains 10 rings, giving you plenty for a larger preserving session or to keep in stock for ongoing use throughout the season.

Practical specifications

These rubber rings are specifically designed for Weck RR100 jars with a diameter of 100 mm. They are best stored at 15–25°C to maintain their elasticity and functionality. Please note that jars, lids, and clips are sold separately, and that the rings are not suitable for the dishwasher, oven, or microwave, as this may compromise their sealing ability.

Frequently asked questions

Can I reuse the rubber rings?

Yes, the rubber rings can be reused, but always check them for wear, cracks, or stiffness before reusing. Replace them if they show signs of deterioration to ensure a proper seal.

How do I know if the seal is correct?

After preserving and cooling, the lid should be held firmly in place by the vacuum. You can test the seal by carefully lifting the jar by the lid (without the clips) – if the seal holds, the rubber ring is correctly positioned.
