Masontops Pickle Pipes Airlock Fermentation Lids Wide and Small Combo Sauerkraut and Pickle Kit Review (2026)

Who this combo kit is for

This kit is aimed at fermenters who like to run a sauerkraut or pickle project across two jar sizes at once, for example a wide mouth jar for a main batch of kraut and a small mouth jar for a side batch of a spicier version or a different vegetable. It is described by the retailer as a sauerkraut and pickle kit, so it leans toward vegetable fermentation projects rather than liquid ferments like kombucha or kefir. Because it mixes wide and small mouth caps in one purchase, it suits someone who owns both jar sizes and wants a matched set of lids rather than buying two single-size packs separately. It is a weaker fit for someone who ferments exclusively in one jar size, since a combo pack delivers fewer caps of that preferred size for the same price as a dedicated single-size pack.

How the Pickle Pipe design works

Each cap in this combo is a one-piece silicone lid with a built-in one-way valve that vents fermentation gas automatically, so there is no water trap to check, refill, or spill, and no daily burping required once the jar is set up. The set covers both wide mouth and small, or regular, mouth mason jars, letting you match the lid to whichever jar size a given batch calls for. The low profile of the caps, compared with a tall traditional airlock, means jars can be stored upright in a cabinet without needing extra clearance above them. The silicone is described as food-safe and BPA-free, built to handle the acidic, gas-producing environment of an active vegetable ferment without degrading. As with all pickle pipe style lids, a metal mason jar ring for each jar size is required to hold the caps in place and must be supplied separately.

Living with a wide and small combo day to day

In practice, this combo works well for someone who likes to compare two versions of a ferment side by side, such as a plain kraut in the wide mouth jar and a caraway or juniper version in the smaller jar, using the matching cap for each. Pack your vegetables and brine, seal each jar with the correctly sized cap and ring, and leave both jars to ferment without needing to check on the airlock itself, since the valve handles gas release on its own. It is still worth checking periodically that vegetables remain submerged under the brine in both jars, since that is the main variable that affects success regardless of which lid style you use. The caps are dishwasher safe between batches, making cleanup no more involved than washing any other kitchen lid.

Trade offs and how it compares with other pickle pipe sets

Against the wide and regular mouth combo sold separately, this kit is marketed more specifically toward sauerkraut and pickle projects, though the practical difference often comes down to exact jar sizing rather than a meaningfully different design. Compared with a single-size three pack, this combo trades quantity for flexibility, giving fewer caps of any one size but covering two jar sizes instead of one. The retailer's own listing notes the fermentation jar itself is not included, which is standard across the entire pickle pipe lineup but worth flagging for anyone assuming a complete kit. Buyers who ferment almost exclusively in one jar size will get more total caps, and better value, from a dedicated single-size pack instead of this mixed combo.

Verdict and who should pick something else

For a fermenter running side-by-side sauerkraut or pickle batches in two different jar sizes, this wide and small combo earns our score of 8.4 out of 10 for matching the retailer's stated use case without forcing a single jar size choice. It suits someone who already owns both jar sizes and wants lids for each without a second purchase. Buyers who stick to one jar size for all their ferments should choose a dedicated single-size pack instead, since it delivers more usable caps for the same money. Anyone who does not yet own the jars themselves should also budget for those and for mason jar rings, since neither ships with this lid-only combo.
