ForJars wide mouth lids and bands are replacement canning lids sized for wide mouth Ball jars, about 86 mm across. The steel is thicker than conventional lids, 0.18 mm against the usual 0.10 to 0.12 mm, with a soft BPA-free sealing compound underneath. They are sold for water bath, pressure, steam and vacuum sealing, and the maker says the seal holds up to 18 months or more. The sealing compound is single-use, so the lids are not meant to be reused for canning, though the bands can be.
