Why not a flow control tap/devices?
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 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.
POK Injection-moulded Design.
Like all new duotights push in fittings all of them are manufactured with polyketone plastic (POK). This aids in chemical resistance, tensile strength, and toughness.
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!
The worlds most compact ball lock disconnect every 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 the only ball lock disconnect that allows standard ball lock kegs to be double stacked while still connected to beer and gas lines.
The overmoulded poppet design means you can couple and disconnect this ball lock disconnect under extreme pressures of 150psi and will never have issues with the o-ring blowing out.
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.
No cheap ABS plastic or nitrile seals. This ball lock disconnect is made from stainless spring and ball bearings, with an engineering polykeytone resin body, EPDM and PP/EPDM overmoulded poppet. This makes this ball lock 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.
