ONEBOM Fermentation Airlock 3 Pack, S Type Airlock Twin Bubble with Grommets for Wine Sauerkraut Making

They work!

If you have brewed before, you know what these airlocks look like and how they work.These were good, and typical of this kind of product.What prompted this review was the good customer service.I THOUGHT the package came with only 2 gaskets but it turned out one had wedged itself in one of the red caps. So I wrote to customer service asking another be sent.They got right back to me with an "of course" and just asked that I make clear the product I was asking about (presumably so there were no errors in what I needed).I let them know my mistake and all if finished. But good customer service by the Onebom Supplier!

Been making a bunch of hot sauce and these work good for fermenting and keeping all the air out!!! Easy to use. would recommend

The media could not be loaded. It's working so far, nothing has exploded. It does not work well with lids i have, but I was able to make it a tight fit with the rubber piece however some air is seeping the around the bottom and it rocks, not to any fault of the item, just not compatible with all lids. I've also noticed that it's leaking some, most likely out of the center bottom where it doesn't fit airtight.

Requires some work to install. Have a drill, bits and a metal file on hand. The stopper fits and a 1/2 inch hole. I made a mistake using a 1/2 inch flat drill bit, the metal tore out (pictured). The solution is to use a few smaller round bits from 1/16 up to 7/32 and then use a metal file to widen the hole out to the desired 1/2 inch.
