Works a Lynette r than the original plastic version.

Haven’t installed them yet. In the process of rounding up all the Ducks.

I like how these look on the kegerator and they prevent any air loss out of the two tubing portals in the back of the kegerator. They allow for a quick disconnect to the two way manifold. Bought a few parts to make a quick connection to the kegs on the inside.

I use this to clean keg lines and to make seltzer water. About 2 years in, no issues or concern. I've probably made a hundred 2L bottles of seltzer, so it has easily paid for itself several times over. I've only ever used it with (grey) gas connectors, the (black) liquid connectors didn't seem to fit. If you are considering it, I highly recommend it.

This is a must have for the Rounder

Well Made. Easy to use versatile

This is awesome for cleaning tap lines. Just fill a empty 2L up with beer line cleaner, screw this on top and push it through the line. Perfect

I used this to make a QD for a beer gun set up. I just attached a piece of hose from the gun to this and connected the coupler from the CO2 line. Works great.

I fill an old (clean) soda bottle with cleaner/starsan/RO water and screw this on the top. Attached bev line QD, open tap, squeeze bottle. Easy peasy.Also works with gas QD so you can carb your favorite concoction in a soda bottle too.

Great product. Does what it says. Much better than plastic caps

First thing you notice, this is a hefty part. Does an excellent job fitting on and sealing 2 litre bottles. I was able to swage the end of a 5mm ID EVA tube to fit on the barbed fitting. In the pic below, I don't have the cap on tight (allows the gas to escape) and I'm using the 2 litre as a blow-off container into StarSan. I have an empty 2 litre with a Cap on, and this allows me to harvest CO2, which will be used when I cold crash, so only CO2 gets sucked in.

If you just going to your boys house to chill why take a glass growler that can break and it’s hard to flush the co2 out of and that you can’t counter pressure fill. These things are super cool and a great option for traveling with home-brew. I took a few old soda bottles camping with me filled with my home-brew. Keeping a Glass growler in the ice chest is sketchy when that same ice chest is full of all your camping food and drinkS for the family. I clean my soda 2-liters with pbw then rinse and fill with star San I then dump the star San and hit the bottles with co2 and I slowly twist off these attachment until I hear the co2 hiss out. I do that a couple times to purge o2. After that I connect the liquid and do the same slow twisting off of this attachment to counter pressure fill the soda bottles. This allows me to use cheap soda bottles and flush o2 and counter pressure fill. I also like to steal a 2-liter early on in cold crashing to sample my newly fermented beer. I have a kegmenter so I can steal from it easily. I put the 2-liter under 30 psi and shake it to carbonate the sample of my new cold crashing beer. Also the post of these work great with either gas or liquid ball lock disconnects. I keep my 2-liters out of the sun so I avoid skunking of my beer too. Cheers.

seals perfectly, much better than the plastic one.

Works great! 1000% better than the plastic carbacap, which doesn’t fit on any bottles!

I totally love my purchase. And am shopping for more things to buy. During our being separated I decided to spend my time constructively. The shopping was fun shipping and transaction easy and fastest shipping I've see. Yet.

Probably one of the best purchases I've made. Counter-pressure filling and carbonating soda type bottles, closed transferring out of carboys by placing it in the carboy cap small barb with a clamp (use caution with pressure and glass), and more.
