This plastic 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!

When using two ball lock caps, we recommend pairing this red plastic cap with a yellow plastic cap so you can easily identify which caps are being used for liquid or gas.

The barb is Duotight compatible. If you'd like to use the cap with 8 mm OD EVABarrier tubing, see DUO100.

For a stainless steel option see KG500.

Will this fit the sides of the x1 collection jar?
Caleb Miller on Jan 6, 2021
BEST ANSWER: Looks like I should since it fits commercial PET soda/water bottles. The spec for the side port of the collector states “ 28 mm PCO 1881 threaded side ports” which it seems is what those bottle threads are from what I can tell.

Carbonation Cap Red
This is much better than the older original design that did not have the DuoTight compatible barb type fitting. I also appreciate that it is available in two colors. Although it is designed to connect to either a Gas QD or a Beverage QD, I am glad that it is available in two colors. I use Red for Gas and Yellow for Beverage which follows the typical DuoTight QD color scheme.

They work GREAT
This Carbonation and Line Cleaning Ball Lock Quick Disconnect works GREAT. It works on both gas and liquid disconnect. I use them for cleaning the disconnect and lines attached to them. I will be ordering more on my next order with More Beer. They work GREAT.

These are a must have!
I have a few of them. Stick one on a ball lock QD to let it flush while applying pressure with another one at the other end. I do have a couple of the stainless steel versions but now I wish I had just stuck with these plastic ones.
