Why FreshLock Pro Outlasts Every Cheap Pump You've Tried

75-83% Oxygen Removal, Gauge-Tested

Independent gauge tests confirm FreshLock Pro hits 75-83% oxygen removal — nearly double what most cheap electric pumps actually deliver.

Works With Any Mason Jar

Whether you use standard or wide-mouth jars, FreshLock Pro handles both with the included converter. Your entire jar collection is covered from day one — no extra purchases needed.

FreshLock Pro

Auto-Stop Pressure Sensor

The built-in sensor stops the pump the instant target vacuum is reached — not on a timer, not by guesswork. Every jar seals consistently.

Always Charged, Always Ready

Each seal uses just 2-3% of the battery, giving you 60 to 100 jars per full charge. USB-C top-up takes a couple of hours.

Frequently Asked Questions

FreshLock Pro removes oxygen to slow staleness and spoilage — it is not a pressure canner and cannot sterilize food for wet canning. It excels with coffee, herbs, grains, and refrigerated leftovers.

Yes. FreshLock Pro is designed for all standard and wide-mouth mason jars, including popular brands like Ball and Kerr. If it has a flat lid, it almost certainly works.

Each seal uses just 2-3% of the battery, so a full charge typically powers 60 to 100 sealing cycles depending on jar size. The 30-day standby rating means it stays ready in your drawer without constant recharging — just grab it when you need it.

FreshLock Pro works well on most fridge items — avocados, sauces, and cut vegetables stay fresher noticeably longer. Avoid sealing hot liquids or carbonated drinks; it is not designed for wet canning.

The device stops on its own once optimal vacuum is reached — you'll feel and hear it click off. The digital display also shows elapsed time and remaining battery so you're always in the loop.

Coffee and herbs that go stale in weeks stay fresh for two to three months when vacuum-sealed. Dry grains that last six to twelve months can hold for two to five years stored cool and dark with FreshLock Pro.

Absolutely. All 10 included caps are built for repeated use. Rinse them with warm soapy water, let them dry fully, and they'll maintain a reliable seal cycle after cycle.

Oxygen absorbers are one-time use and need replacing every time you open a jar. FreshLock Pro removes up to 83% of oxygen with a reusable valve lid, which handles everyday pantry and fridge storage on its own.

FreshLock Pro, a mason jar vacuum sealer, is used for dry goods such as coffee, herbs and grains, and for refrigerated items like sauces and cut vegetables. Hot liquids and carbonated drinks should not be sealed with it.

The jar vacuum sealer kit includes the FreshLock Pro device, a USB Type-C charging cable, five large wide-mouth sealing caps, five standard-mouth sealing caps and one lid opener tool.

FreshLock Pro: A Mason Jar Vacuum Sealer for Pantry Jars

FreshLock Pro is a mason jar vacuum sealer for kitchens that store coffee, herbs, grains and refrigerated leftovers in glass jars. The handheld device sits on a flat jar lid and starts with a single button.

Its built-in pressure sensor stops the pump on its own once target vacuum is reached, and a digital display shows elapsed time and remaining battery. To vacuum pack mason jars, the kit includes five standard-mouth and five wide-mouth sealing caps, which are rinsed with warm soapy water and reused.

As an electric mason jar sealer, it charges over a USB-C cable. A mason jar vacuum sealer like this one is not a pressure canner, so it does not replace water bath or pressure canning.

  • Standard and wide-mouth jar compatibility
  • USB Type-C charging cable
  • Lid opener tool included
