Mason Jar Vacuum Sealer - Upgrade Canning Sealer Kit for Mas

The Verdict

If you’ve ever watched a $200 electric vacuum sealer struggle with a Mason jar attachment, you know the frustration. This upgrade kit takes a simpler approach — one that actually works. Here’s the real story.

What’s Actually in the Box

The kit includes two lid attachments (one for regular-mouth, one for wide-mouth jars), a hand pump with a pressure-release button, and a set of reusable vacuum lids. The pump body is machined aluminum with a rubber grip — it feels solid, not like a toy. The sealing attachments have a silicone gasket that creates the seal against the jar rim.

The key upgrade over cheaper kits: both jar sizes are included. Most budget options force you to buy a second kit for wide-mouth jars. That’s a genuine cost saver.

How It Performs in Real Use

I tested this on dry beans, coffee beans, and dehydrated fruit over two weeks. The process is straightforward: attach the lid, pump until you feel resistance, and the vacuum indicator pops down. For a regular-mouth jar, expect 20-25 pumps. Wide-mouth jars take a bit more.

The seal holds. I left a jar of coffee beans vacuum-sealed for five days — the lid hadn’t budged, and the beans stayed noticeably fresher than the control jar. The included vacuum lids have a small indicator button that stays depressed when sealed. One buyer noted, “I was skeptical about a hand pump, but it pulled a stronger vacuum than my electric sealer on jars.”

Where it shines: dry goods, spices, coffee, dehydrated snacks, and even prepped meal ingredients. It’s also genuinely portable — take it camping or to a cabin and you’re not dependent on electricity.

What Buyers Consistently Praise

Across the 225 ratings, three themes dominate. First, the seal quality: “Finally a sealer that actually holds on wide-mouth jars” is a recurring sentiment. Second, the build quality — the aluminum pump doesn’t feel like it’ll crack after a month. Third, the simplicity: no hoses, no electricity, no complicated settings.

Where It Falls Short

The pumping gets old. If you’re sealing 15 jars of dehydrated produce, your arm will feel it. This is not a bulk-processing tool — it’s a small-batch solution.

Liquids are a problem. If you try to vacuum-seal soups or sauces, you’ll pull liquid into the pump mechanism. You need at least an inch of headspace, and even then, it’s risky. This is for dry storage, not canning liquids.

The indicator is subtle. The button on the lid is small and the visual change is minor. If your eyesight isn’t great, you’ll be pressing the release valve repeatedly to check.

No jar included. Some competing kits throw in a jar to start you off. This one doesn’t.

Who Should Buy This

This is for you if you’re a home dehydrator, a coffee enthusiast who buys beans in bulk, or a gardener who wants to extend the life of dried herbs and spices. It’s also ideal for RV owners or off-grid folks who want vacuum sealing without electricity.

Skip it if you’re a serious canner processing quarts of soup or sauce — you need a real vacuum sealer with a jar attachment or a traditional water-bath canner. And skip it if you’re sealing more than 10 jars at a time regularly.

FAQ

Q: Can I use this with any Mason jar brand? Yes — the attachments fit standard Ball, Kerr, and generic Mason jars. The vacuum lids are universal-fit for regular and wide-mouth sizes. Just don’t use it on decorative jars with non-standard rims.

Q: How long does the vacuum actually last? In my testing, sealed jars held vacuum for at least two weeks. One buyer reported a jar sealed for over a month still had the indicator depressed. It depends on the quality of the lid gasket and how clean the rim is.

Q: Can I reuse the vacuum lids? Yes, that’s the point. The included lids are reusable — just wipe them clean and re-seal. The gaskets will eventually wear out, but they’re replaceable.

The Verdict

Rating: 4.6/5

Buy it if you want an affordable, portable way to vacuum-seal dry goods in Mason jars without buying a bulky electric machine. It’s well-built, does what it claims, and the two-size inclusion makes it a genuine value.

Skip it if you’re sealing liquids or processing bulk batches — the hand pumping becomes tedious fast, and liquid contents will compromise the pump.

For the home preserver who works in small batches and values simplicity, this is the kit to get.
