Packs contains 10x seals.
Seal size 100mm is the most common size (for Weck jars 290ml and larger)
100mm seals are suitable for both size sourdough jars in our kits:
Jar Size 370ml - sold without seal and clamp (buy a seal here if required)
Jar Size 850ml - already includes a seal and clamp (buy an additional seal if required)
Sourdough fermentation does not require a sealed and clamped jar. Sealing your jar makes it air-tight, providing additional food storage and preserving options.
CLAMPS are required to clamp the lid down tightly on to the seal for air-tightness
