Since foam is all a factor of beer line resistance, temperatures AND "obstructions"....what would this cause? I'm guessing there will be some turbulence caused by this and thus CO2 breaking out at this point. What would be the "net effect" as far as how many feet of line would have to be added just to off-set the affect of the splice?

Say for example, you estimated you needed 3 extra ft of line to balance your current system. Because of the "slice affect" do you actually need 3 + "x" feet of line?

I couldn’t get my eva barrier lines on the end of my shank so I bought splicers and increased the line size an inch before going into the tap shank. I have no foaming issues.

fwiw...Dremel off those shank barbs...

Then use 5/8" BSP to 8mm (or 5/16") PTC adapters. I used DMfit but iirc both John Guest and Duotight have solutions for this end...

I thought you meant Dremel off the tails on the hose clips for some weird reason.

Then got further down the post to see the reason. I use the PTC adapters and they are fine.

I think that a narrowing obstruction into a bigger space might cause nucleation but the beer is flowing quite slowly.

I get it, but maybe "future folks" that look at three clamps to make one connection will take the alternative route :)

Cheers!

well, after comparing some of my shanks...there is still the issue of that huge void in some of the shanks that may cause turbulence and/or let beer get stale from sitting...seems that tiny hole in the solid shank is better, but the spring assist shanks have a huge open area, allowing beer to sit stagnant for a while.

need to consider the beer line as a "whole system" from keg to glass...

Is the line length just about "slowing" the flow? Various "things" in the beer route can cause CO2 to break out...slowing the beer speed is just one of many things that reduces that "break out"?
