Suitable for two types of Mason jars: The electric Mason jar vacuum sealer includes two sizes of sealing rings for everyday use. To obtain standard-mouth sealed jars, simply insert the red arrow into the standard-mouth sealing adapter, align it with the unlock symbol on the main unit, then insert it into the silicone ring of the wide-mouth sealing area. Tighten clockwise until the arrow aligns with the lock symbol, indicating successful installation.

Meet all your vacuum sealing needs: Our food vacuum sealer kit helps remove air from Mason jars, extending the shelf life of stored food.

Easy to Use: This cordless vacuum sealer comes with a standard-mouth sealer converter kit, compatible with both wide-mouth and regular-mouth Mason jars (Mason jars not included). Ensure the electric vacuum sealer is centered and firmly pressed against the jar lid. Click the button to start the vacuum pump, waiting approximately 60 seconds or longer for air to be drawn out to seal. Click the button again to turn off the sealer.

Electric Vacuum Pump, Hands-Free Operation: No more manually pumping a vacuum pump ten to twenty times with both hands. No more digging through a pile of accessory hoses and vacuum machines that clutter your countertop. With our electric vacuum pump, simply press the button once, wait 60 seconds, and your vacuum seal is complete.
