North Mountain Supply regular mouth safety button lids are designed to fit most standard regular mouth mason jars with a 70 mm opening, including popular brands like Ball, Kerr, and North Mountain Supply. Each gold metal lid features a continuous thread finish and an integrated safety button that provides a visible indication of vacuum seal status.
Inside each lid is a BPA free plastisol liner that softens with product heat, creating a tight, hermetic seal as it cools. The 70 450 closure profile and ribbed neck are designed for dependable sealing performance and easy tightening by hand.
These lids are recommended for hot fill products where contents are filled hot and allowed to cool and seal. For water bath processing at higher temperatures, North Mountain Supply recommends using their compatible hi heat lids. Always follow appropriate tested recipes and safe canning guidelines for your specific use.
