If you want an easy way to balance your beer lines, this is the way to do it. One of the benefits of Flow Control disconnects is you don't need to rely on the small ID or line length to apply flow resistance. Rather than adjusting your line length or size, simply apply additional restriction directly on the Quick Disconnect (QD). This is perfect for people who want to serve a large range of beverages with differing carbonation levels without having to customize each line. Now with the added benefit of Duotight fittings built in.

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. 

The humble plastic ball lock disconnect has been around a long time and is used by countless homebrewers around the world.  Despite the extensive use they have seen little to no innovation for decades and KegLand wanted to change this. Enter the Duotight Ball Lock QD. The integrated Duotight design means you can connect your beer and gas line directly, easily and reliably with no need for additional fittings or clamps. It is a robust and super compact design that is incredibly easy to assemble and disassemble, making cleaning and sanitizing an absolute breeze!

Made from highly chemical resistant materials with stainless springs and ball bearings (no cheap ABS plastics here) this baby is extremely resistant to commonly used chemicals such as phosphoric based sanitizers and caustics. The incredibly small form factor allows for easy stacking of kegs. The new cap design ensures a pressure seal with just hand tightening and it can be completely taken apart for cleaning with no tools required.

Features:

  • Ball Lock Quick Disconnect - Bev Out
  • Adjustable flow rate
  • Direct connect EVABarrier tubing
  • Compact design won't interfere with keg stacking
  • Made from highly chemical resistant materials
  • Dissamble by hand for quick and easy cleaning

 

  • Works as described. Good foam control. No leaks so far.
  • Great for bottling from the tap. Just create a slow pour and bottle away.
  • Very good fortune using these for line balancing while keeping lines short.

Very Good Product

I have had very good fortune using these to give me line balancing while keeping the lines short. I used to use expensive flow control faucets but I think these are a better alternative.

Extremely hard to seat the 8mm EVA tubing.

I don't know if I got a bad batch I purchased four of these along with five sets of 8MM EVA tubing four duotight gas QDs four 8MM fittings and four inline regulators. I was able to seat the tubing in every other item but these with ease. The gas QDs did take a bit more pressure to seat but these flow control QDs required the use of pliers to hold the tubing while I twisted and turned the QD to get the tubing to seat fully. Once seated I haven't noticed any leaks in the only one I've connected to a keg.

Great product. Fast shipping.

This little beauty works as described. Good foam control. I like the duotight system. No leaks so far.

Great!

These are great for bottling for the tap. No reason to change the gas pressure just create a slow pour and bottle away.

Works fine my only complaint is that sometimes is difficult to use it in some kegs pots

Where does the black o-ring go exactly when reassembling these?

Can this completely shut off flow? I want to use it as a liquid shut off on the Nukatap Counter pressure bottle filler instead of a valve when filling directly from a keg.

MoreCoffee!

Yes but the problem you may have is turning the knob with one hand the whole disconnect will swivel on the ball lock so you may need to use 2 hangs which may defeat your purpose.

MoreCoffee!

I only have 1 and it's the only one I've ever owned but yes it can completely shut off flow to the line.

MoreCoffee!

Yes. This product will completely shut off the flow when turned fully clockwise. Enter an answer to this question.

MoreCoffee!

I got it down to a drop every couple seconds. Not sure if that was just residual pressure/carbonation in the line or if it doesn’t completely close but it seems like it’s pretty good. It takes a bit of turning to shut it’s not quick like a ball valve FWIW.

MoreCoffee!

Yes they can.

MoreCoffee!

Yes it can shut off flow completely but I doubt it would be as quick as a regular valve -- mine are kind of hard to turn. I paired it with my CP filler and was very happy with the results. I was able to run a shorter line between the keg and filler than previously. Cheers!

MoreCoffee!

Yes this can shut off flow completely.

Does clockwise on the flow control knob decrease the flow or increase it?

MoreCoffee!

Decrease

MoreCoffee!

clockwise closes the valve decreases the flow. I turned mine all the way open counter clockwise and put a mark on the dial with a sharpie so I can keep track of how far it is closed to get the best pour.

The description indicates "you should use either shorter line or larger ID line that you would when compared with traditional ball lock disconnects." Any recommendations regarding specific length of line and ID combinations?

MoreCoffee!

I'm sorry. I see where you read that. Although the line ID is fixed personally I will just decrease the line length to the shortest i can. To me that's the advantage of those disconnects.
