wide mouth lids and bands

Listings commonly show neck diameters of about 3.3 inches, 3.38 inches, and 3.5 inches for wide-mouth lids.

Pack sizes range from small multi-packs (for example, 12 pairs) up to much larger counts such as 72, 144, and 288 lid-and-band pairs. Some listings show combinations like 432 lids paired with 144 bands.

Descriptions commonly note a BPA-free sealing compound for airtight seals. Some lids also use silicone gaskets to create an airtight barrier that helps prevent air or odors from entering or escaping.

Special types include child-resistant lids with push-down-and-twist locking mechanisms and inner dividing tubes, and fermentation airlock lids made of silicone with one-way waterless valves for venting.

Listings often include overall and piece-specific dimensions—for example: 0.56 inches high × 3.56 inches wide; 3.5 inches wide × 0.6 inches high; and 3.25 inches wide × 0.12 inches high. Some listings also provide packaging dimensions for multi-packs.
