JILLMO 1L Square Fermentation Jar Kit, 2-Pack with Airlocks & Weights — Wide-Mouth, Airtight

JILLMO 1L Square Fermentation Jar Kit is a two-pack of heavy-duty 1-liter glass fermenting jars that include airtight lids, silicone caps, weights, and airlocks to make reliable, hands-off fermentation simple.

Whether you're starting with sauerkraut, pickles, kimchi or small-batch hot sauce, this complete kit supplies the essential glassware and hardware to keep ingredients submerged and gases vented safely. The jars are made from thick, lead-free glass with a wide 3.3" mouth for easy packing and cleaning, and each set includes two fermentation weights plus extra silicone caps so you can prepare multiple batches or swap parts as needed.

How does this kit make home fermentation easier?

The kit combines airtight lids with a 3-piece airlock system so carbon dioxide escapes while oxygen and contaminants stay out. The included weights hold vegetables under brine, preventing spoilage and off-flavors without daily burping. Designed to be dishwasher-safe, the jars simplify cleanup after fermentation is complete.

• 3-piece airlocks vent gas automatically to reduce maintenance
• SUS304 hinged clip and silicone seal create a leak-resistant seal
• Heavy 3" diameter weights keep food submerged under brine
• Wide mouth (3.3") permits easy packing and handwashing

Will these jars keep my ferments airtight and leak-free?

Yes — each jar uses a glass lid with a silicone gasket plus a stainless steel (SUS304) hinged clip to secure a tight seal. A silicone cap for the airlock further reduces splashes and contamination. The combination minimizes leaks and helps maintain an anaerobic environment that's ideal for lactic fermentation.

• Silicone seal under the lid for airtight closure
• SUS304 clip ensures durable, rust-resistant fastening
• Silicone airlock cap prevents splatter while allowing gas release

What sizes and components are included in the 2-pack?

Each kit contains two 1-liter square glass jars sized for small to medium batches, plus two fermenting weights, two 3-piece airlocks, and two silicone caps with two extra caps for replacements. The weights are roughly 7–9 oz and measure about 3" in diameter with handles for easy removal.

• Two 1L square lead-free glass jars (wide 3.3" mouth)
• Two heavy fermenting weights (7–9 oz, 3" diameter with handle)
• Two 3-piece airlocks and four silicone caps (two extra caps included)

How do I clean and maintain these fermentation jars?

All glass components are dishwasher-safe, and the wide mouth allows easy access for hand washing or scrubbing. Remove the silicone gaskets and airlocks for separate cleaning to prevent trapped food residues. Store lids and silicone pieces dry to prolong the gasket life and maintain airtight performance.

• Dishwasher-safe glass jars for quick cleaning
• Disassemble airlock pieces and silicone parts before washing
• Dry seals and clips thoroughly before storage to avoid corrosion
