This stainless steel flow control disconnect will eliminate the guess work of balancing draft lines. Use the adjustment knob to dial in the ideal flow resistance based on the beverage being served. Flow control disconnects perform better than flow control faucets as they put the point of resistance at the beginning of the beverage line instead of at the end. When beer passes through the flow control apparatus inside the faucet, turbulence will cause carbonation to come out of solution and foaming issues occur. Flow control disconnects 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.
Please note: make sure your keg post o-rings are in good condition before using this fitting. If they are overly worn and you are not getting a good seal, replace the post o-ring then re-attach the ball lock fitting.
