Description

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

Looking to reduce beer line length
Matthew V on Feb 21, 2023
Eliminates the need for a long hose when dispensing from a keg which is great for a portable keg situation where you want to take as few extra items as possible.

I uses a sankey to ball lock adapter. The commercial kegs are always over carb. Trying these to reduce foam.

my O rings failed on prior flow control and this should have less weight making it easier to use

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.
Jonathan Hughes on Mar 1, 2023
BEST ANSWER: 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!
Does clockwise on the flow control knob decrease the flow or increase it?
David Lange on Jan 9, 2023
BEST ANSWER: 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?
Jeffrey Hewit on Aug 24, 2022
BEST ANSWER: 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.

Pin pressure and can't push 8mm tubing in. Beer leaks out where the tubing goes in because I can't slide it in like I can with the duotight fittings
Can't get the 8mm evabarrier tubing to push in passed the rubber gasket also unsure if it has enough pin pressure. at 20psi I'm getting 18 seconds to pour a pint. That's wayyyyy slow for 18psi at 5 feet of tubing

not enough pin pressure
The spring doesn't put enough pressure on the post pin to release liquid under 15 psi 1 bar.

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.
