Vacuum-sealing a Mason jar keeps dry goods like flour, coffee, nuts and pasta fresh for far longer than a lid alone. The right tool depends on one question: do you already own a vacuum sealer?
Attachment or standalone?
A jar sealer is either an attachment that uses your existing vacuum sealer's suction, or a standalone cordless unit that needs no machine. Attachments are cheaper if you own a sealer; standalone units are the answer if you don't.
If you own a FoodSaver: the FoodSaver attachment
The FoodSaver jar sealer is the top pick for machine owners: inexpensive, hugely reviewed, fits both jar mouths, and includes the accessory hose. It just works with any FoodSaver that has an accessory port.
Match the tool to what you already own. Don't buy a cordless unit if you have a FoodSaver, and don't buy an attachment if you have no machine to plug it into.
If you don't own a machine: the VP06+ cordless
The VP06+ is a rechargeable, cordless sealer that vacuums jars on its own, one press, no hose, no machine. It costs more than an attachment but saves you buying a whole vacuum sealer just to seal jars.
The budget attachment: mason jar sealer kit
The two-piece kit covers both jar mouths and includes the hoses for the least money, a fine choice if you want an attachment and don't need the FoodSaver name.
The verdict
Own a FoodSaver? Get the FoodSaver attachment. No machine and don't want one? Get the VP06+ cordless. Want the cheapest attachment? The mason jar sealer kit. Jar sealing keeps pantry staples fresh for months, though for decades-long storage, mylar and absorbers still win.
If you own a vacuum sealer, the FoodSaver jar sealer attachment is the best and cheapest way to seal Mason jars. If you don't, the VP06+ cordless sealer does it standalone. The two-piece kit is the budget attachment. All fit both jar mouths and keep dry goods fresh for months.
Frequently asked questions
What does a jar sealer do?
A jar sealer attachment pulls the air out of a mason jar and seals the lid, using a vacuum sealer or a handheld unit. It is ideal for dry goods, coffee and leftovers you open often, since the jar reseals.
Can you vacuum seal regular mason jars?
Yes. Standard wide-mouth and regular-mouth mason jars work with jar sealer attachments, using ordinary two-piece lids. The vacuum holds the flat lid down; you reuse the jar and ring indefinitely.
Is jar sealing good for long-term storage?
It is excellent for medium-term pantry storage and anything you open regularly, but glass is breakable and takes more space than mylar for a deep reserve. For decades-long staples, mylar in a bucket is more practical.
