Includes one silicone valve lid and one stainless steel wide mouth band / ring. Fits any *wide mouth* (3″ internal diameter) Mason, Ball, or canning jar.
Our silicone valve lid for wide mouth Mason jars will revolutionize your small batch fermentation! The “bubble” on the top has a slit cut in it. When pressure builds up in the jar, the lid bulges up. This automatically opens the slit and lets the CO2 produced by fermentation escape.
No more burping and no more topping up the water in the airlock! No more exploding jars or bent lids! Easy to clean - both parts are dishwasher safe!
Made of 100% silicone rubber, these lid inserts are dishwasher, freezer, and microwave safe! Silicone is a safe, green, non-plastic (BPA free) material for food use that does not leach any chemicals. Made of 304 grade 18/8 stainless steel, the band will not rust and is also dishwasher safe!
