70 mm, Band Metal Caps, Silver Plastisol Lined Canning Bands

Silver jar caps in a two piece construction are a top choice when canning in various methods. The first piece is a threaded band that will screw tightly to 70 mm glass jars. The second piece is the plastisol lid that creates a hermetic seal when properly heated and cooled. The thread ban of the jar caps can easily be used repeatedly, whereas the plastisol lid is a one use piece. Purchase each piece of the jar caps separately, or together, and click the Add-Ons for the array of 70 mm glass jars that are compatible.
