Artcome 32 PC Fermenting Airlock Lids Kit Set for Large Wide Mouth Mason Jars Review (2026)

What it is

This is a 32-piece fermenting accessory kit built around six stainless steel lids, six water airlocks, ten silicone sealing rings, and ten silicone grommets, all sized for large wide mouth mason jars. The airlocks use a water-seal design, where fermentation gas bubbles out through a small reservoir of water while outside air is blocked from getting back in. Because the kit supplies six full lid-and-airlock sets rather than one or two, it is aimed at people setting up multiple jars for a batch of vegetables, or running several different ferments side by side.

Fit for the job

For anyone doing lacto-fermented vegetables like sauerkraut, kimchi, or pickled peppers in mason jars, a water-seal airlock lid is one of the more reliable low-maintenance options, since it vents gas automatically without daily burping. Six lid sets is enough to convert a whole shelf of jars to fermentation duty in one purchase, which is convenient for batch cooks or anyone stocking up before a harvest. The kit assumes you already own or will buy wide mouth mason jars separately, since none are included, so factor that into setup cost if you are starting from zero.

Build and materials

The lids are stainless steel rather than plastic, which holds up better under repeated use and resists absorbing odors or staining from brine over time. The silicone rings and grommets are the parts doing the actual sealing work, sitting between the lid and jar rim and around the airlock port to keep the water seal airtight. With 32 total pieces spread across four component types, this kit has more small parts to track than a basic single-lid product, and losing a grommet or ring can mean a lid no longer seals properly, so a dedicated storage container for the kit is worth setting up from day one.

Value

Covering six jars in a single kit brings the per-jar cost down noticeably compared to buying six single lid-and-airlock sets separately, which is where this kit's value case is strongest. It suits anyone planning to run a full batch of jars through a fermentation cycle at once, such as during peak cabbage or pepper season, rather than someone who only ever ferments one jar at a time. If your kitchen only has room for one or two jars going at once, a smaller two or four pack from a comparable brand may be a better use of shelf space and money. Spare grommets and rings beyond the six needed for the lids also give some cushion against normal wear over a season of use.

Who should buy it

This fits home fermenters scaling up from a single test jar to a full shelf of active ferments, or anyone who wants a season's worth of lids on hand without reordering mid-batch. It is a reasonable match for someone new to fermentation who wants to try several vegetables at once rather than committing to just one. It is less useful for someone who ferments occasionally and only needs one or two jars going, where a smaller kit with fewer spare parts to lose would be simpler to manage. Households that preserve seasonally, stocking up during a harvest glut of cabbage or peppers, will get the most consistent use out of having six sets ready to go at once.
