Duotight Flow Control Ball Lock Quick Disconnect (QD) | Beverage Out | Adjustable Flow Rate | 8 mm Duotight

    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.  

    Flow Control QD vs. Flow Control Faucet
    One of the only drawbacks of flow control devices is that they inherently create a small amount of turbulence and therefore can cause foaming. In the past, flow control faucets have been the only common option. Flow control faucets are very popular but due to the fact that they are placed at the very 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.

    Duotight Ball Lock QDs
    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.

    Duotight Push-to-Connect
    These Duotight ball lock disconnects already have the Duotight fitting built into the ball lock disconnect. No need for additional threaded fittings. Simply push the beer/gas line in and you are done!

    Compact
    The world's most compact ball lock disconnect ever manufactured. This new compact form factor is great for tight spaces or fridges where you want to pack as many kegs in as possible. This is one of the only ball lock disconnects that allows standard ball lock kegs to be double stacked while still connected to beer and gas lines.

    Overmolded Poppet
    The overmolded poppet design means you can couple and disconnect this ball lock QD under extreme pressures of up to 150 psi (higher than most kegs working pressure) and will never have issues with the o-ring blowing out.

    Tool-less Disassembly
    Other ball lock disconnects require a tool such as a flat head screw driver or spanner to take them apart for cleaning. The new caps on these allow for easy disassembly by hand, making these easier to break down for cleaning. It's literally never been easier to remove hop particles from your ball lock disconnects.

    Extreme Chemical Resistance
    No cheap ABS plastic or nitrile seals. This ball lock disconnect is made from stainless spring and ball bearings, with an engineering polyketone resin body, EPDM and PP/EPDM overmolded poppet. This makes the quick disconnect resistant to extreme chemicals such as phosphoric and acetic acid, caustic soda, peroxide and many other acid or base chemicals which are commonly used in homebrewing.

    Toughness
    This ball lock disconnect is more robust than any other plastic ball lock disconnect ever manufactured due to the use of new engineering plastics. Don't be fooled by the small form factor — these bad boys are tough!

    Features:

    • Ball Lock Quick Disconnect - Bev Out
    • Adjustable flow rate
    • Direct connect 8 mm EVABarrier tubing
    • Compact design won't interfere with keg stacking
    • Made from highly chemical resistant materials

        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?

        MoreBeer!

        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.

        MoreBeer!

        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.

        MoreBeer!

        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.

        MoreBeer!

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

        MoreBeer!

        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.

        MoreBeer!

        Yes they can.

        MoreBeer!

        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!

        MoreBeer!

        Yes this can shut off flow completely.

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

        MoreBeer!

        Decrease

        MoreBeer!

        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?

        MoreBeer!

        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.

        MoreBeer!

        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.
