The FoodSaver V4440 is the best vacuum sealer for mason jars for most people. Its listing names regular and wide-mouth mason jar sealers as optional accessories, it has an accessory port, and a built-in handheld sealer covers containers too. If you want published suction, the Beelicious Pro VS8001H declares 95 kPa and an external port for jars and containers.
A bar sealer cannot close a jar on its own. It needs an accessory port, a hose and a jar sealer lid attachment. We only list sealers whose listing declares a port or canister function. Every figure comes from the official listings; we have not sealed jars with these machines ourselves.
What does a sealer need to vacuum seal jars?
An accessory port, a hose and a jar sealer attachment that fits your jar mouth. The sealer pulls air out through the hose, the flat lid is held down by the vacuum, and you lift the attachment off.
- Accessory port. A socket on the sealer where the hose plugs in. All six models here declare one.
- Hose. Several listings include one: the FoodSaver FM2100, ROUUO SV628 and MEGAWISE VS6621 mention it.
- Jar sealer attachment. A cap that sits over the jar mouth. Regular and wide-mouth jars need different sizes. None of these listings says a jar attachment is included; the V4440 lists them as optional.
- A canister or accessory mode. Some sealers have a button for it: the ROUUO SV628 lists Canister Vacuum and the Beelicious VS9313 a Canister function.
Which vacuum sealers are best for mason jars?
These six all declare an accessory port or canister function. Empty cells mean the listing does not publish that figure.

The Nesco VS-12 is missing on purpose: its listing does not declare an accessory port. It is a good bag sealer, but not for jars.
Pick by what you need
The best vacuum sealers for mason jars
The V4440 is the only listing here that names mason jar sealers directly, in both regular and wide-mouth sizes. That makes it the most straightforward choice if jars are your main reason to buy a sealer. It also has a retractable handheld sealer built in, which covers FoodSaver containers and zipper bags.
For bags, it detects moisture automatically and has roll storage and a cutter. The downsides: the jar sealers are optional extras, the listing does not publish suction, and FoodSaver does not publish a device weight for it. The official V4440 page confirms a 5-year limited warranty.
Pros
- Listing names regular and wide-mouth mason jar sealers as accessories
- Built-in retractable handheld sealer for containers and zipper bags
- Automatic moisture detection, roll storage and cutter
Cons
- Jar sealers are optional, not included
- No kPa or device weight published
- Best for
- Pantry jars plus everyday bags
- Skip it if
- Small counters

The VS8001H’s listing mentions jars by name: its external vacuum port extends use to jars and containers. That gives you strong bag sealing and jar sealing in one 2.5 kg (about 5.5 lb) machine.
It adds a double seal and three moisture modes, so it also handles marinades and sous vide bags. The warranty is described as 2+ years, and the listing does not say which jar attachment, if any, is in the box.
Pros
- External vacuum port that the listing says extends use to jars and containers
- 95 kPa dual pump and double seal
- Dry, Moist and Extra Moist modes
Cons
- Warranty stated as 2+ years
- Jar attachment not listed as included
- Best for
- Jars, sous vide and wet food

The FM2100 declares an accessory port and hose, roll storage with a cutter and dual heat sealing strips. It is 120 W and 3.0 kg (about 6.6 lb) with a 5-year warranty.
It does not publish suction, and the title says dry and moist food without naming a moist mode. For jars of dry goods, that gap matters less than for wet bags.
Pros
- Accessory port and hose
- Dual heat sealing strips
- 5-year limited warranty
Cons
- No kPa figure
- No named moist mode
- Best for
- FoodSaver users who want a double seal

The VS9313 is our overall pick for bags, and its Canister function covers jars and containers. It ranks lower here only because the listing says less about jars than the V4440 and VS8001H.

- 5-year warranty
Cons
- Bag width not published

How do I vacuum seal a mason jar?
Fill with dry food, wipe the rim, place a flat lid, cover it with the jar attachment and run the accessory mode. Here is the step by step:
- Use a clean, dry jar with a rim free of chips.
- Fill with dry food, leaving about 1 in (2.5 cm) of space below the rim. Put powders like flour or cocoa in a paper filter or cupcake liner on top, so dust is not sucked into the hose.
- Wipe the rim clean and dry.
- Place a flat lid on the jar, without the ring.
- Fit the jar sealer attachment over the lid and connect the hose to the accessory port.
- Run the canister or accessory function until the sealer stops.
- Remove the hose, then lift off the attachment. Press the lid center; it should not flex.
- Screw on the ring loosely for storage, and label the jar with the contents and date.
If the lid pops up, clean the rim, try another lid and repeat. If the sealer runs but never reaches vacuum, see why a vacuum sealer is not vacuuming.
What should I store in vacuum-sealed jars?
Dry, crushable or often-opened foods benefit most. A jar protects crackers, chips and dried fruit that a bag would flatten, and you can reseal it after each use.
| Food | Why a jar works well |
|---|---|
| Dried fruit and vegetables | Keeps out moisture from the air; see our dehydrators for fruit |
| Jerky (fully dried and cooled) | Stays dry without crushing; see how to make jerky |
| Nuts, seeds, coffee | Less oxygen slows staleness |
| Crackers and chips | Rigid jar stops crushing |
| Rice, beans, pasta | Easy to reopen and reseal |
For storage over months or years, jars let in light. Mylar bags with oxygen absorbers block light, air and moisture; see long-term food storage.

Frequently asked questions
Can any vacuum sealer seal mason jars?
No. You need a sealer with an accessory port and hose, plus a jar sealer attachment that fits the jar mouth. Check the listing for the port; the Nesco VS-12, for example, does not declare one.
Do I need a regular or wide-mouth jar sealer?
It must match your jars. The FoodSaver V4440 listing names both regular and wide-mouth mason jar sealers as optional accessories.
Is vacuum sealing a jar the same as canning?
No. It removes air but does not heat-process the food. Moist, perishable food in a vacuum jar still needs the fridge or freezer.
What foods are good to vacuum seal in jars?
Dry food: dried fruit, jerky, nuts, crackers, rice, beans, coffee, dried herbs. Jars also protect crushable snacks that a bag would flatten.
Why won’t my mason jar lid stay sealed?
Usually a chipped or dirty rim, a bent or reused lid, or food dust on the rim. Wipe the rim, use a flat undamaged lid and try again.
