Frequently Asked Questions



FoodSaver® Jar Sealers

The Mason jar will not vacuum

The Jar Sealer is designed for use with Ball® and Kerr® Mason jars. Check Jar Sealer to see if it is centered and pressed firmly over Mason jar lid. Make sure rubber gasket on Jar Sealer is free from food materials. Examine rim of Mason jar for cracks or scratches. Any gaps can prevent jars from vacuuming properly. Check metal lid of Mason jar to see if it is bent. Make sure Accessory Hose is securely in Accessory Port on appliance and on Jar Sealer. Try using two jar lids instead of one. Remove second lid from Jar Sealer when vacuum process is finished.

Why is the Jar Sealer no longer included in FoodSaver® packages?

We used to include the Wide-mouth Jar Sealer in our packages, but our new canister lid styles no longer require Wide-mouth jar sealers.
