Xelyra Fermentation Lids for Wide Mouth Mason Jars, 6-Pack with Date Tracker, Airlocks, Silicone Rings and Grommets Review (2026)

Who this kit is for

This set is aimed at fermenters who want to outfit several jars in one purchase rather than buying lids one or two at a time. Each of the six complete sets includes a lid, airlock, silicone ring and grommet, and the kit is built to fit standard wide mouth jars ranging from about 4 ounces up to 64 ounces, so it can cover everything from a small test batch to a full quart of kimchi or sauerkraut. The built-in date tracker on each lid is a small but useful touch for anyone who ferments in batches and tends to lose track of which jar was started when. People who only ferment in one jar at a time, or who already own airlock lids, will get less value from buying six sets at once.

How the lid and airlock system works

The lids themselves are stainless steel, paired with plastic airlocks and food-grade silicone rings and grommets that seal the jar while still letting gas escape. The airlock is a one-way system, meaning built-up carbon dioxide from active fermentation can bubble out through the valve while outside air is largely kept from getting back in, which is the same basic principle used across most airlock-style fermentation lids. This reduces how often you need to manually burp a jar compared with a plain screw-top lid, since the airlock handles gas release on its own once it is set up correctly. Because the kit covers a wide jar-size range, the same lid can move between different jar volumes as your fermenting projects change from week to week.

Setting up and living with six lids on rotation

Assembly is simple: the grommet seats into the lid, the airlock clicks or screws into the grommet, and the silicone ring sits between the lid and jar rim to seal it before threading the whole assembly onto a wide mouth jar. The date tracker dial on top lets you set the day a ferment started so you do not have to rely on memory or a separate label when jars start to stack up on the counter. Cleaning the parts is straightforward since airlocks and grommets typically separate for washing, though as with any multi-part lid system, buildup around the grommet seal is worth checking periodically to keep the one-way valve working properly. Running six sets at once means less swapping of hardware between jars mid-ferment, which matters if you keep several batches going in parallel.

Where it sits against other airlock lid kits

Compared with a 4 pack of stainless steel airlock lids from an established brand like Jillmo, this Xelyra set offers two more complete sets for a similar footprint, plus the date tracker feature that many rival kits skip. Against a kit like Easy Fermenter's 4 pack, which has built a longer reputation in the fermentation space, Xelyra is a newer name, so buyers who prioritize a long history of customer feedback may lean toward a more established brand even if the parts list looks similar on paper. None of these kits include the glass weight needed to keep vegetables submerged, so budget for that separately regardless of which lid system you choose, since an airlock lid alone does not hold produce under the brine line.

Bottom line and who might look elsewhere

For fermenters who want to equip a whole shelf of jars with matching airlock lids and appreciate the date tracker for keeping batches straight, this 6-pack is a practical, well-rounded choice that lines up with its strong marks for fit and value. The main caveat is that Xelyra has less of a track record than some of the longer-standing names in fermentation gear, so if brand history matters to your buying decision, that is worth weighing. Anyone who only needs one or two lids, or who already owns a weight and lid system they like, will not gain much from the larger 6-pack format.
