FoodSaver Jar Sealers
The jar sealer works with any FoodSaver vacuum sealing system (machine not included). Simply connect one end of the jar sealer to the machine's accessory port and the white, round-shaped end to the top of a lidded Mason jar, so that it fits securely over the screwed-on lid.
With the push of a button, the system quickly extracts all the air from inside the jar, pulling it out through the flexible tubing to form an air-tight seal.
