        Good product

        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.

        Nifty and durable

        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.

        Good cheap cleaning option

        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

        used for a beer gun

        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.

        Easiest line flushing

        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.

        Does what I need it to do

        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.

        I love this.

        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.

        Wonderful products super fast shipping

        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.

        Must have for plastic bottling and pressure transferring from carboys

        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.

        Do you sell a replacement gasket for the inside?

        Can you attach a carbonation stone (e.g. KEG590) if you remove the barb?

        MoreWine

        No the cap’s internal fitting is not a flare. Get a stone with a barb and connect with tubing… or get a barb with a flare fitting and attach to the one you pictured.

        I want to use this for a gas line quick connect on the back of the Komos V2 kegerator. What do I need to get to convert the quick disconnect to accept the gas line? I know what I need for the barbed side.

        MoreWine

        The fridge includes a Duotight fitting for the gas line to attach to the regulator so the simplest thing to do (and what I'm doing) would be a gas ball lock with its own Duotight fitting--Morebeer's item number is DUO150. Screw the included fitting onto the regulator cut a length of the EVABarrier line push one end into the fitting on the regulator push the other end into that ball-lock and you're set. The other option would be to use the included hose barb. Screw that onto the regulator instead of the Duotight fitting and then it'd be regular hose and ball lock.

        MoreWine

        Just purchase a ball lock gas line quick disconnect. They have barbed or MFL threads to hook up to the gas line regulator.

        How do you get the spring clip back in after cleaning?

        Sorry. I use this for beer line cleaning so have never taken it apart.

        The description says that this is compatible with liquid ball lock connectors. Doesn’t fit my liquid ball lock connector for my keg system. I wanted to use it to clean my liquid lines as described in the product description. Is there a trick to pushing it into the the liquid ball lock connector?

        MoreWine

        Why not just fill your keg with cleaner and run it out through the faucet and into a receiving vessel? Or am I missing the point of your question?

        MoreWine

        Hi David. It's meant to carbonate beer in PET bottles. Try a gas fitting and see if that works.

        MoreWine

        Just a bit of sanitizer to lube it and it should work fine

        MoreWine

        It should fit either liquid or gas ball locks. It’s a tight fitting o-ring so you might try some keg lube and try again.
