Is this the same elbow fitting that you used?

And if so, I guess all your fittings and tubes are 1/2in and this fitting is the only 1/4in to 1/2 in. Does that constrict the flow at all? I need one but was hoping to find one that was 1/2in to match the rest of my fittings......
Also, where can I find those double threaded fittings you have? (red circles)
