How to Vacuum Seal Mason Jars with FoodSaver: Gear Compared

FoodSaver is one of the best-known names in home vacuum sealing. Most people know it for countertop machines that suck the air out of plastic bags, but the brand also sells handheld sealers and a jar sealer attachment that lets you vacuum seal ordinary mason jars. Removing air slows down staleness and freezer burn, which is why jars of coffee beans, nuts, dried beans and homemade jams keep better once sealed.
In one sentence: the two handheld sealers and the compact countertop machine are the power sources, the FoodSaver jar sealer is the official attachment, and two of the jar sealer kits here are third-party products from other brands built to work with FoodSaver machines.

What a Jar Sealer Attachment Actually Does
A jar sealer is a plastic cap that fits over the top of a mason jar. You place a flat canning lid on the jar, press the jar sealer over it, and connect a thin hose from the sealer to the accessory port on a vacuum machine. When the machine pulls air out, the flat lid is sucked down tight. Once you remove the jar sealer, the lid stays in place until you pry it open. Mason jars come in two opening sizes: regular mouth and wide mouth. A foodsaver regular mouth jar sealer fits the smaller opening, and a foodsaver wide mouth jar sealer fits the bigger one. Vacuum sealing is for fresh storage, not a replacement for proper canning.

FoodSaver Handheld Vacuum Food Sealer Machine
Best for: Quick sealing of zipper bags and containers
Pros
- Cordless handheld design
- Charging cord included
- Works with FoodSaver zipper bags and containers
Cons
- No charging dock included
- Listing gives few details
The FoodSaver Handheld Vacuum Food Sealer Machine (FS1120) is a cordless FoodSaver handheld vacuum sealer made for FoodSaver zipper bags and FoodSaver vacuum seal containers. The listing is brief: it says the sealer comes with a charging cord but not a charging dock. The specifications list manual operation, plastic construction and a multicolor finish.
The listing also gives a wattage of 300 watts, which is an unusual figure for a small handheld; we would treat it with caution. The listing does not specify battery life, whether it can connect to the jar sealer, or what bags come in the box.
This is a simple choice for someone who wants to seal zipper bags and containers quickly. If you want a dock, a marinate mode or clearer battery details, the newer Mini Handheld below gives more information and more features.
FoodSaver Plastic Jar Sealer for Official Mason Jar Sealing

FoodSaver Plastic Jar Sealer for Vacuum Sealer Food Storage with Accessory Hose for Regular and Wide Mouth Mason Jars
Price and specifications are read from the Amazon product page and can change.
FoodSaver Plastic Jar Sealer for Vacuum
Best for: FoodSaver owners starting jar storage
Pros
- Wide and regular mouth sealers
- Accessory hose included
- Dishwasher safe, BPA free
Cons
- Needs a vacuum machine with accessory port
- Listing contents slightly inconsistent
The FoodSaver Plastic Jar Sealer is FoodSaver’s own mason jar kit. The description says it includes one wide-mouth jar sealer, one regular jar sealer and one accessory hose, which covers both jar sizes. Note that the listing is a little inconsistent: the “included components” line mentions only the regular sealer and hose, while the description and the three-count unit total both point to all three pieces. Check the box on arrival.
The listing says the kit is for mason-type jars and is great for sauces, mustards and jams. It is described as odor proof, stain resistant, dishwasher safe and BPA free. It needs a vacuum machine with an accessory port to work; it has no pump of its own.
This is the pick for anyone who already owns a FoodSaver machine with an accessory port and wants the official attachment. If you do not own a machine yet, the BUVLIVU kit with a hand pump is the easier way to try jar sealing.
Mason Jar Vacuum Sealer and Manual Pump for Sealing Without a Machine
Best for: Jar sealing with a sturdier gasket
Pros
- Upgraded rubber seal ring
- Adapter and lid opener included
- Wide and regular mouth sealers
Cons
- Third-party, not made by FoodSaver
- Not compatible with several FoodSaver models

Mason Jar Vacuum Sealer and Manual
Best for: Sealing jars with or without a machine
Pros
- Manual hand pump included
- 10 spare jar lids
- Lid opener included
Cons
- Third-party, not made by FoodSaver
- Odd power specs in listing
The Mason Jar Vacuum Sealer and Manual Portable Vacuum Pump is a third-party kit from BUVLIVU, not a FoodSaver product. It includes one wide mouth jar sealer, one regular-mouth jar sealer, two hose connectors, one manual vacuum pump, one lid opener, a user guide, five wide-mouth lids (86 mm) and five regular-mouth lids (70 mm).
The listing says its food grade silicone hose works with most FoodSaver vacuum machines and names models such as V3230, V2440, V2244, V3400 and V2862, among others. The manual pump is the big difference: if you do not have a FoodSaver machine, or you are traveling, you can pump the air out by hand. The kit is made of ABS plastic, is BPA free and can be cleaned by hand or in the dishwasher. Oddly, the listing also gives a wattage of 300 watts and a voltage of 230 volts for what is a manual kit, which seems to be a listing error.
This suits beginners who want to try a mason jar vacuum sealer before buying a machine, or FoodSaver owners who want spare lids and a lid opener in one box.
FoodSaver Mini Handheld Vacuum Sealer Machine for Marinating and Small Spaces
Food Saver
FoodSaver Mini Handheld Vacuum Sealer Machine with Marinate Setting & Charging Dock, Cordless Food Vacuum Sealer for Freezer, Storage, Sous Vide, Meal Prep, Blue
Price and specifications are read from the Amazon product page and can change.
FoodSaver Mini Handheld Vacuum Sealer Machine
Best for: Small kitchens and fast marinating
Pros
- Auto Marinate Mode
- Charging dock included
- Up to 35 quart bags per charge
Cons
- Liquids only in Marinate Container
- Jar sealer use not specified
The FoodSaver Mini Handheld Vacuum Sealer Machine is a rechargeable, palm-sized sealer with a charging dock. The listing says it charges in 2.5 hours and seals up to 35 quart bags per charge, with color-coded LED lights for sealing progress, charging and battery level. Auto Off stops the vacuum when sealing or marinating finishes.
Its standout is a one-touch Auto Marinate Mode that works inside the included Marinate Container to infuse flavor in minutes. Liquids must stay in that container; the listing warns it is not designed for liquids otherwise. In the box: the sealer, charging dock, two quart zipper bags, two reusable quart zipper bags and a 3-cup container. The description says it is compatible with FoodSaver accessories, but the listing does not specifically confirm jar sealer use, so check before relying on it for jars. Our FoodSaver mini vacuum sealer guide explains the handheld range further.
This is a fun gift for someone who meal preps or marinates often. For big freezer batches, the Compact countertop machine is better suited.
FoodSaver Compact Vacuum Sealer Machine for Freezer Storage
Best for: Freezer storage with bags and rolls
Pros
- Dry and Moist settings
- Stores vertically
- Starter roll and bags included
Cons
- Corded
- Jar accessory port not described
The FoodSaver Compact Vacuum Sealer Machine is a corded countertop sealer that stores upright to save space. The listing says it keeps food fresh in the freezer up to 5x longer than ordinary storage, seals with 35% less bag waste than previous models, and offers Dry and Moist settings for different foods.
It comes with one 11-inch by 8-foot roll, three quart bags and two gallon bags, and works with all other FoodSaver bags, rolls and accessories. The listing says it connects to a FoodSaver Hand Held Sealer (sold separately) for fridge and pantry storage, but it does not describe a hose accessory port, so the listing does not specify whether jar sealers connect directly. Stock up with our guide to FoodSaver bags.
This suits a first-time buyer who mainly wants freezer bags for meat and batch cooking. For jar-focused storage, confirm the port or pair it with a hand pump kit.
Mason Jar Vacuum Sealer with Adapter for a Tighter Fit
The Mason Jar Vacuum Sealer from Lafinynp is another third-party kit made to work with FoodSaver machines. It includes a wide-mouth sealer, a regular-mouth sealer, a hose connector, an adapter, a lid opener and a manual. The listing highlights an upgraded rubber gasket that will not pop out after vacuuming and a longer seal to fit different jar shapes.
The hose connects to FoodSaver machines using the adapter and to other machines with an external suction port. Importantly, the listing says it is not compatible with several models, including FM2000, FM2100, FM2500, FM2900, FM4800, FM4900, FM5800, VS0160, VS1130, VS0100, VS0150, VS220 and FM1100. It lists 110 watts and corded electric power, even though the kit itself has no motor.
Choose this if your FoodSaver has an accessory port and is not on the incompatible list. If you need a hand pump, the BUVLIVU kit is the better match.
How to Choose the Right FoodSaver Jar Sealer
First, check what you already own. A jar sealer needs suction from somewhere: an accessory port on a FoodSaver machine, or a manual pump. Look for a small round port and hose on your machine, and check the model number against the third-party compatibility lists.
Second, match the jar sizes. All three jar kits cover both regular and wide mouth jars. The BUVLIVU kit also adds ten spare lids, which is handy for beginners.
Third, decide official or third-party. The FoodSaver Plastic Jar Sealer is the brand’s own kit; BUVLIVU and Lafinynp are other companies making compatible parts.
Finally, if you do not own a machine, read our overview of the FoodSaver vacuum sealer range before deciding which FoodSaver to buy.
FAQ
How do you vacuum seal mason jars with a FoodSaver?
Put a flat lid on the jar, press the correct-size jar sealer over it, connect the accessory hose from the machine’s port to the sealer, and run the vacuum. Remove the sealer once the lid is pulled down.
Do I need both regular and wide mouth jar sealers?
Only if you use both jar sizes. All three kits here include both.
Can I seal jars without a FoodSaver machine?
Yes, with the BUVLIVU kit, which includes a manual hand pump.
Are the third-party jar sealers made by FoodSaver?
No. BUVLIVU and Lafinynp are separate brands whose kits are designed to work with FoodSaver machines.
Does the FoodSaver Compact machine work with a jar sealer?
The listing does not describe an accessory port, so it does not confirm jar sealer use. Check the machine itself before buying a kit.
