Description

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!

Features:

  • Liquid and Gas Ball Lock Compatible
  • Disassembles for Easy Cleaning
  • Made from Stainless Steel
  • 28mm PCO 1881 Threads

Please note: The threaded section of the bottleneck must be at least 1/2" long to form a seal. These caps are not compatible with the KegLand 500mL PET Bottles.

What is the size of the barb? Is it 1/4"?
JamesC814366206 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.
Are the quick disconnects on this just the KG500 or KG502?

How do you get the spring clip back in after cleaning?
Richard R on May 7, 2021
BEST ANSWER: Sorry. I use this for beer line cleaning so have never taken it apart.
Is the barb permanently attached, or can it be removed?
Daniel P on Dec 3, 2020
BEST ANSWER: Assuming they are the same as when I got them last year, they are permanently attached.
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?
David M on Jan 8, 2021
BEST ANSWER: Just a bit of sanitizer to lube it and it should work fine
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.

KOMOS® Kegerator | NukaTap® Stainless Steel Faucets | Fan Cooled Stainless Tower | Digital Thermostat | Casters | Regulator | Fits 1 Half Barrel Keg or 4 Corny Kegs
BEST ANSWER: 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.

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

BEST ANSWER: 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.

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.
