Vac&Stack Mason jar Vac Lids 5-Pk (Wide Mouth with Pump)

The small, flat Check Valve in the center of the Vac&Stack Mason jar Vacuum Lids saves space by letting you stack your vacuum-packed Mason jars on top of each other. Since the small Check Valve only extends 1/4 inch (6 mm) below the Mason jar lid, the white Cap used to prevent food from contacting the Original Check Valve was eliminated. As with our Original ThriftyVac Vacuum Lids, the Wide Mouth Vac&Stack Vacuum lids keep your vegetables, meats, and liquids fresh in your refrigerator for months. You can repeatedly vacuum pack any Mason jar, reopen it, and reseal it. The Vac&Stack Vacuum Lids are available in both Regular and Wide-Mouth sizes, and are sold in packs of five. The Regular size and Wide-mouth size Vac&Stack Mason Jar Vacuum Lids fit jar mouth diameters of 2.5 inches and 3.375 inches, respectively. The Vac&Stack Vac Lids are dishwasher-safe. All ThriftyVac Vacuum Lids are BPA-free.
