0.6% acetic acid solution scares you? hmmm ... most people I know (including me) use it in undiluted form (5% solution) for thorough cleaning/flushing of every new component before installation like blocks and radiators, 1-2 hours long bath in undiluted vinegar is not uncommon either ... I made a mistake of running the 0.6% for too long and all the cheap thin Nickel fittings corroded.
problem here was an atrocious workmanship on the Nickel plating of some fittings which started flaking off (since it wasn't perfect to start with) in prolonged presence of very mild acetic acid, mind that it didn't harm any other component except for those with Nickel or Silver plating, mostly ones made by Bitspower, one by Koolance, a few Dark Chrome ones from XSPC and one by EK (this one was worst quality)... the rest is super clean and shiny, really, believe it or not.
as per wrenches, Swiftech recommends using them, check their website for Lok-Seal fittings.
the lesson I learned here is that I do not buy "shiny looking" fittings anymore, especially not from Bitspower. For Bitspower I make only one exception: brass core fittings and electro-coated with black paint.
With Swiftech the chrome plating looks OK (and is actually a chrome plating), but under it there is a layer of Nickel too, most other companies simply call their fittings "chrome" because it looks like it while it is actually Nickel.
also, so you know in case you haven't checked the whole thread, the PT Nuke Copper Sulphate is also something that Nickel plating doesn't like ... especially if it's been weakened by presence of Silver in same loop. that's another lesson I learned and sharing it here without much of shame, so more can learn and avoid same costly mistakes.
actually that loop was built after listening to advice of many "experts" in various forums that ignored simple manufacturing facts related to some shiny parts and ignored potential of corrosion when pH gets disturbed, e.g. by using PT Nuke Copper Sulphate and/or when Silver is present in same loop. I don't hold grudge against them, could have checked myself, now I know and want others to realize that too.
most people seeing this thread just jump put and yell "OMG vinegar in the loop" like it really mattered all that much here ... vinegar solution used here, is not of much importance, the fact is that perhaps it accelerated only what already was going on since over a year in a loop that was considered safe before and the most important fact is how poorly made are the most expensive compression fittings and adapters, that's the bottom line.Edited by feniks - 8/23/13 at 2:18pm
