Carbonation and Line Cleaning Ball Lock Cap - Plastic

60 day no hassle return policy. Details

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!

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.

A massive improvement on the CarbCap
If you're sick of CarbCaps forming a crappy seal and/or breaking outright, welcome to the future. This puppy interfaces relatively easily with gas and liquid ball locks, forms a very good seal with absolutely no effort (no need to over-tighten whatsoever), and is just a super hand way to, say, run sanitizer through beer line

Grab a few

Very good product, need more customer service.
These work very well. However it would be great if you would have also included the part numbers for the tubing that fit the this ballock connector.

difficult to seal
Its good except the bottle must have a perfect top edge, otherwise it won't seal tight.
