This is an excellent upgrade to our mini keg and growler tap systems.
One of the problems with small beer dispensing systems like ours is that in a full size kegerator you would usually have around 2 metres of beer line between the keg and the tap. This is left long for a good reason and there are a whole range of calculators out there to help you find the optimum length for your setup depending on the diameter of your lines, height from keg to tap etc.
Basically by increasing the length of the line you increase the amount of pressure you can have the regulator set to and still pour a good beer, if the lines are too short and the pressure is at the optimum 10-12psi you will just blow foam out the tap.
You can still pour a beer with a lower pressure. This is how you would use our system usually, you set the pressure between 3-5psi and pour like that however there is a drawback.
Without a pressure of above 10psi the CO2 from the beer will not be held in a dissolved state and will begin to go flat. This means that each time you finish pouring a beer you should increase the pressure to 10psi and then when you want to pour again release it back down to 3-5psi, wasting gas and valuable drinking time.
With one of these adaptors in place between the disconnect and the tap you can adjust the flow till you are pouring the perfect beer with the pressure set to what it would be in a bar / kegerator. Then use the included allan key to lock the adaptor in place and there is no fiddling anymore, just leave the pressure set to 10 psi till you finish the keg.
