Description

Sleep a little easier knowing this gas in ball lock with built-in check valve has your back. The internal check valve allows gas to flow out, but won't allow backflow of liquid into your gas system. Many manifolds and regulators already feature check valves, but this disconnect will keep liquid from ever entering your gas lines in the first place. Especially handy if you force carbonate your beer using the bev out dip tube!

Why we love it:  Because we've had beer shoot back into our gas line and that sucks. At some point you will have a keg that is pressurized more than the pressure in your gas system. This could be caused by different carbonation levels, a keg sitting at room temperature, etc. So for example if the pressure in your keg is at 20 psi and your regulator is set at 12 psi, when you connect your gas in quick-disconnect liquid shoots from the keg into the gas line. Eliminate that possibility with this ingenious fitting.     

Features:

  • Internal Check Valve protects your system from liquid back flow
  • Made in Germany and assembled in the USA by CMB.
  • Extremely high quality for years of service.
  • NSF Approved for Food Grade Service!

Thought it would be good, for my 4 way carbonating manifold, as liquid has a tendency to get in the gas lines making it hard to clean.

Loved the idea of a check valve to protect by gas system.

Will this work with 5/16 gas line, or only 1/4 line?
Marc Mendelsohn on Mar 4, 2020
BEST ANSWER: The other answers are correct that this can be used with any size of tubing as long as you have the appropriate size flare and barb combo.
Does it require a flare washer?
Lanz Van Beurden on Aug 16, 2019
BEST ANSWER: Hi Lanz - this disconnect features a built-in clear plastic washer and does not require an additional nylon flare washer to function properly.

Works as it should
Perfect for what it does. No more beer getting into the gas lines.

Worth it!
Not cheap, but replacing a regulator because of backed up fluid is MUCH more expensive! Just get this for every gas-line keg connection and enjoy having one less thing to worry about. It is cheap insurance.

Interesting device
There has been many times when shaking to carbonate, the liquid would flow into the co2 line. This necessitated taking the co2 line apart and PBW and Star Sanning it. RPITA. I also have a small 5lb tank I use to carbonate 1 lt test batches. It too, upon occasion, would back up the gas line. In my 6 product line kegerator, when I connected a new corny keg, unequal pressure between keyg and co2 would cause the same thing. This hopefully would prevent that. So far so good. The 3 star rating is for the 9 kegs in my temp controlled freezer. After I depressurized the kegs and replaced the with this item on the kegs no beer was moved the 14' above to the faucets . 14 psi worked to get a good flow before but the gas wasn't going into the kegs at 14 psi. I gradually increased the gas till i heard in flowing into the kegs, 19 psi was the point that the gas flowed. I let it flow for a while, then reduced it back to 14. We'll see if I don't get enough pressure after I dispense and need to turn it back up. I hope this isn't the case.
