Phobya SLI VID Internal Diameter?

[grandpatzer]

Anyone measured or can make a guess on the ID on the metal tubing (thin part).
Not sure what to make of it, looks like it's just 5-6mm ID, even in paralell gpu's looks lite not good for a system with 19/13mm tubing?

~5/16in or 8mm

This is a measured value by you or a guess?

If it is 8mm ID seems like if I use 2 of them in paralell I get more flow through cards then if I had used serial with one 19/13 fitting (G1/4 Bore size 9.8mm).

Approximation because I measured with a ruler and MK.1 mod.0 eyeball.

Thanks, If I run 2 phobya sli for paralell I actually get more flow vs serial with 19/13 compression fittings
