Carbonation and Line Cleaning Ball Lock Cap - Stainless

In Stock
60 day no hassle return policy. Details

This stainless steel ball lock cap features soda bottle threads, allowing you to convert a 1 or 2 liter soda bottle into a convenient travel growler. The ball lock is compatible with both gas and beverage disconnects, so you can charge the PET bottle before you leave the house and dispense on the go. Attach 3/16" or 1/4" ID tubing to the barb to serve as your dip tube and you're all set!

These caps also work great for quickly and conveniently cleaning your draft lines. Mix up a small batch of line cleaning solution in a soda bottle, attach the ball lock cap, and then connect it to your beverage line. Place a bucket below your tap to catch the cleaning solution and open your faucet. Then simply turn the bottle upside down and squeeze it to push solution through your line and out the faucet. You can also choose to pressurize the bottle first, but squeezing the solution through is just as effective.

Fermenting with the FermZilla? This is the same ball lock fitting included with the FermZilla Pressure Kit and it's also compatible with the FermZilla Collection Container. If you use the collection container to add dry hops, attach one of these caps and you'll be able purge the container of oxygen before opening the dump valve to introduce the hops. Attach some tubing and diffusion stone and you can oxygenate your wort through the collection container as well!

Great way to serve from PET bottles. Also can be used to cleanly add flavorings, etc. to a keg w/o allowing O2.

What is the size of the barb? Is it 1/4"?
James Cruz on Mar 25, 2020
BEST ANSWER: The barb is 1/4" OD and will fit any 1/4" ID tubing. We always recommend using hose clamps when dealing with pressurized systems.

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.

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.
