ForJars Regular Mouth Canning Lids & Bands are 70mm two-piece lids with thicker steel than conventional lids: 0.18 mm against the usual 0.10 to 0.12 mm. The underside sealing compound is BPA-free, and the lids are rated for water bath, pressure, steam and vacuum sealing, with seals said to hold up to 18 months or more. They fit regular mouth Ball jars and suit canners who reuse lids across seasons and want a sturdier lid than the thin disposable type. The trade-off is that they are a single-size regular mouth set, so wide mouth jars need a different lid.
