Flow is great, does what
"Flow is great, does what it says, great on the oxebar kegs. Does foam up a little on first pour but great once you get used to it"

If you want an easy way to balance your beer lines this is the way to do it. Please be aware that even in the fully open position these FC disconnects do have some inherent flow resistance so you should use either shorter line or larger ID line that you would when compared with traditional ball lock disconnects. One of the benefits of FC disconnects is you don't need to rely on the small ID or line length to apply flow resistance so it would not make sense to use long lines or small ID lines as well as this is the job of the FC device.
This is perfect for people who want to serve a large range of beverages with differing carbonation levels as it gives you the ability to adjust resistance easily. Now with the added benefit of duotight fittings built in.
This particular ball lock disconnect has been designed to suit 8mm Beer Line. Due to the integrated duotight fitting the line will simply push directly into this fitting.
This all new ball lock disconnect sets a new bar! The integrated duotight design means you can connect your beer line directly, easily and reliably - no need for additional fittings or clamps. It is a robust and super compact compared to the previous Stainless Steel Flow Control Ball Lock that has been discontinued due to the difficulty in repeated tooling and overall cost of raw materials.
Flow control devices are good but they inherently can create a small amount of turbulence and therefore can cause foaming. In the past flow control taps have been the only common option. Flow control taps like these ones are popular however they have the issue that due to the fact they are placed right at the end of the beer line they have no head pressure. As a result any turbulence created can cause foaming and carbonation to come out of solution.
Flow control ball lock disconnects like these on the other hand have the ability to restrict the flow before the beer enters the beer line so the head pressure created by the beer line keeps the carbonation in solution. Even in the instance that high turbulence is created the beer will be far more resistant to foaming issues. For this reason flow control ball lock disconnects like these have significantly better performance allowing you the flexibility to adjust line resistance easily but without the introduction of turbulence that creates foaming. It cannot fix over-carbonated beer, but it can reduce the amount of beer line you would need to pour without excessive foaming.
Some of the features include:
duotight Swivel Elbow Sold Separately

If you are often pulling your beer and gas line sideways we recommend the use of the duotight male to female elbow as this allows your gas to swivel 360 degrees without making a kink in the beer/gas line.

"Flow is great, does what it says, great on the oxebar kegs. Does foam up a little on first pour but great once you get used to it"
"Works surprisingly well. And fairly compact. Works great with the nuka tap mini"
"Not overly happy with the use of these. . the tap part is really hard to adjust, even after disassembling and a good lubing. A great design, but would buy the metal one if it was still available."
"Excellent products. Very user friendly."
"I've got a couple of these brand new and it seems there is no way to remove the duotight adaptor once installed. The collet just won't release it. I've got the 7 way tool that's help you pull the duotight fittings but even with that it just won't let go."
"Makes pouring easy!"
"Initially I thought they were a good product. Then one failed and just would not allow flow so I cleaned it thoroughly by pulling it fully apart and it just failed again and again. The only particulate matter was yeast, which had settled. Then another failed in the same manner and then another. This is not a good product. Complete redesign for the pin that provides flow."
"Works well to dial in pour/flow rate and reduce foaming with shorter lines. Can also use it directly on the ball lock post of a mini keg with a nukatap mini for a portable setup!"
"Works well"
"Fits well, can run short lines, pours perfect"
