Accessories for Weck Jars

Since their creation more than a century ago, Weck jars have naturally found their place in most European kitchens. Perfect for storing cereals, pasta, rice and flour, they are also ideal for fermenting vegetables, preserving jams and even presenting attractive verrines.

To help you use yours for many years, Conservor has selected official Weck jar accessories suitable for all available formats: glass lids, metal clips and rubber seals. Order everything you need now to make your preserves successfully!

The main Weck jar accessories

The success of Weck jars is based in particular on an ingenious system of complementary accessories that ensure complete airtightness and safe sterilisation. There are three main accessories: lids, seals and metal clips. Made from high-quality materials, namely glass and natural rubber, they guarantee virtually unlimited use of the jars.

Weck glass lids

Essential components of Weck jars, the removable lids are made from transparent or lightly tinted glass, making it easy to visually check the level and general appearance of the preparation, although this alone is not enough to verify the quality of the preserve.

Available in several diameters, from 40 to 100 mm, they can be reused indefinitely as long as they remain intact, and can simply be washed in the dishwasher.

Rubber seals

The seals used with Weck jars ensure airtightness between the jar and the lid. During sterilisation, they are compressed by the heat and the clip, creating the vacuum needed for preservation. Inserted into the inner groove of the lid, they are therefore essential for proper food preservation. These seals are made from natural rubber and are BPA-free. They must be replaced after each sterilisation, as this process causes them to lose their elasticity, and it is impossible to check with the naked eye whether they are still sufficiently intact to guarantee proper airtightness.

Weck metal clips

These final accessories are instantly recognisable thanks to their iconic arched shape, characteristic of the brand. The metal clips are used to hold the lid in place during sterilisation. Simply place one on each side to apply firm pressure without damaging the glass. Suitable for all sizes, shapes and capacities of Weck jars, they can be reused for life, just like the lids.

When should you replace your Weck jar accessories?

To ensure your preserves are successful, it is important that the accessories protecting your jars are in good condition. Their lifespan varies: rubber seals naturally stretch during sterilisation, which means they must be replaced after each use. Heat compresses and deforms them, creating cracks and irreversible loss of elasticity.

Steel clips and glass lids, on the other hand, can be reused for life as long as they are not damaged. Clips only need to be replaced if they appear rusty or bent, while glass lids are almost indestructible. Both can be cleaned in the dishwasher, although it is recommended to clean the lids carefully to avoid any residue.

Other Weck jar accessories are also available from Conservor, including freshness lids, which come in the form of reusable plastic lids. These wear out very little, but as soon as they show cracks, it is recommended to replace them to reduce any risk of bacterial growth.

For maximum safety, adopt the right habits: use a new seal for each sterilised jar and always inspect the other accessories visually and manually before use. These simple steps help guarantee healthy, long-lasting preserves, in line with Weck manufacturers’ recommendations. Store them in a dry place away from light to extend their lifespan.
