After seing the build for second time i realized its parallel config but still i cannot see in the post you mention the minimum flow required for the blocks to work efficiently (ml/min)
Also, i certainly know about the Lck Seal male to male conector, but since i made the mistake not to order a couple from you, and currently its not available in Europe , i need an alternative solution, if the parallel bridge does not work as expected with my limited flow. In that case i need to know the exact length of the bridge tube required and not the adjustable length of lock seal that would be definately the best solution...
