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.
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.
This little beauty works as described. Good foam control. I like the duotight system. No leaks so far.
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?
It goes at the bottom below the spring. Check out this photo - https://photos.app.goo.gl/AS99ncnF4VKp858w9
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.
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.
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.
Yes. This product will completely shut off the flow when turned fully clockwise. Enter an answer to this question.
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.
Yes they can.
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!
Yes this can shut off flow completely.
Does clockwise on the flow control knob decrease the flow or increase it?
Decrease
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?
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.
Actually the description says you "don't need to rely on the small ID or line length." That's the whole point of flow control. With these disconnects you should be able to use whatever line length you want and just adjust the flow control to restrict the rate of flow as needed. As far as ID goes these only work with 8 mm line.
