## Description

Homebrew Guys White Silicone Grommets and StoppersHome brewing and making your own fermented products at home is fun, easy and can save you a lot of money in the long run.Fermenting your own food is also healthy. Not just because you know what has gone into it but fermented products also have proven health benefits.Fermented foods have been used for thousands of years and scientists have proven their health benefits. Fermentation is one of the oldest forms of food preservation.Eating fermented foods helps you maintain good gut flora, the 400+ species of bacteria in your intestines that are vital for health.Essentially, eating fermented food gives you a natural dose of probiotics which keep the gut bacteria healthy so that they can do their job in keeping you healthy.To ensure that the Carbon Dioxide that builds up in fermented containers is vented off, you will need an airlock which allows the Carbon Dioxide gas to bubble out and not allow Oxygen back into the container (usually jar or bucket) which may spoil the food.To ensure you get a good fit between the container and the airlock you will need grommets.Our grommets have all of these benefits: - BPA-Free for you safety and peace of mind- Durable and washable - Multi-use, whether you are making your own fermented food or drink, you can use our grommets - Our grommets come with stoppers so you can plug the container when required e.g. cleaning the airlock or to plug the grommet once the fermentation period is over WHAT YOU GET IN THE PACK: 12 x White Grommets + 12 Matching White Stoppers in one plastic bag Purchase one for yourself and consider purchasing one to surprise a friend.

### ⭐⭐⭐⭐⭐ It's obvious upon inspection - the best I've ever seen
*by J***N on September 16, 2016*

These grommets and plugs truly are of premium quality, as they claim. It's obvious upon inspection - the best I've ever seen. The durometer of the silicone is perfect and the finish very smooth. They work great.Because the axial depth of the groove between the upper and lower sides of the grommet is 1/16", these are excellent for fitting into plastic jar lids of any practical size, Tattler canning lids, plastic bucket lids,etc. They might fit Fido jars and some other bail top jars which have thinner lids. But I haven't tried that combination. For Anchor Hocking bail top jars, which have thicker lids, I found it necessary to order red silicone rubber grommets, which have an axial groove depth of 3/8" from Grainger (part# 3MRR8). On my Fido jars, I used the Grainger grommets because they were all I had at the time.The diameter of the groove recession is 5/8" and that is the size hole to be drilled into the lid (same for the Grainger grommet). I believe going smaller to 1/2" will not only make for difficulty in installing grommet, but also fitting the airlock. Comments?The diameter of center hole for fitting the plug or airlock is, of course, 3/8".Relevant(?) side note: You might find this useful. The Dewalt 5/8" diamond drill bit I ordered from Home Depot does NOT actually measure 5/8" diameter, but rather 43/64" instead - just shy of 11/16". You might be OK with that. I wasn't. It would likely work well enough since plug or airlock would presumably stretch the grommet to fit, but as I had already drilled before discovering the discrepancy, I carefully filled in the gap between glass and grommet with clear silicone, using a toothpick in order to make cleaning easier (yeah, made a hobby of it). We'll see if that actually works. It may be easier to just remove grommets for cleaning in the long run. What I'm saying here is that you might want to try another brand diamond drill and be sure of actual diameter. For drilling plastic lids I find it easiest to use a step drill. Enough already.

### ⭐⭐⭐⭐⭐ Essential equipment for lactofermentation
*by J***T on February 4, 2017*

These are of great quality; made from a soft and pliable yet tough and strong, sanitary food-grade silicone. I use these in the lids of plastic wide-mouth gallon jars for lactofermentation, with water airlocks. A standard 3/8" stem diameter airlock is easy to insert and remove yet seals well against the grommet, and it in turn against the lid.They fit perfectly in the 5/8" inch diameter holes I drill in the jar lids with a brad point drill, and would obviously also work well in the lid of a plastic pail or the similarly thick white plastic lids of high quality food storage bowls.Once the fermentation cycle is complete, the included silicone stopper seals tightly and lets you store your vegetables, sauerkraut, etc in the fridge with the same lid. I've used regular black rubber hardware store grommets and bark corks before, but these are much better in every way, and will last forever.

### ⭐⭐⭐⭐⭐ DIY fermentation buckets with airtight seal
*by D***E on March 19, 2017*

So I've been doing a bunch of small batch cabs and pinot noirs, testing different yeasts (ASM, M4, BM4x4, RC212). I buy the 2 gallon white food grade buckets at Lowes along with the 2 gallon lids. On the lids, I drill 1/2in holes, and put these rubber grommets in them. It takes alot of finger strenght to get these grommets in 1/2in hole, but you can do it. With the air lock installed (after SG <1.01), these buckets make airtight seals and bubble away, unlike the buckets from home depot. The lowes lids have a rubber seal in the lid, and home dept does not.You can do the same thing with 5-gallon buckets and lids with these. I plan on buying more.
