Plasticizer Problems / Discussion / Gallery - Page 154

post #1531 of 3087
UPDATE:

I promised to post pictures and give feedback once i stripped down my rig and changed the tubing, after the last fiasco with Primochill.

2 months ago i removed my Blue Primochill UV LRT tubing and those of you that read my prior post, saw the ridiculous amount of plasticizer in them. I ordered some Durelene, and as an interim solution, i used some old Feser UV clear tubing i had stashed away in my storeroom, till the Durelene arrived.

I just stripped the rig again last night (2 months later) and what follows are pictures.


The Feser tubing is 13/10 mm, i used WFI (water for injections-NOT SALINE-its of a purer quality than top grade distilled water),silver kill coil,2 drops Mayhem's extreme biocide & two drops of Mayhem's blue dye.

The blocks and the tubing were much clearer than the previous venture that used Primochill (and yes i mean after a two month time frame).

There was some some staining of the Feser tubing, but that is 100% normal-ALL DYES STAIN TUBING. There was also some miniscule staining in my blocks, but nothing to write home about.


GPU WATERBLOCK:





CPU WATERBLOCK:- it had just a bit of crap in the fins, but thats to be expected after running my rig 24/7 for two months, and under load for at least 6 hrs per day.




Tubing: I have to be fair and say, that apart from the obvious staining, there were traces of plasticizer-BUT NOT ON THE SAME SCALE AS PRIMOCHILL (the blue tubing is a piece of the old primochill that i had kept for personal reference purposes,the difference is self evident). The Feser tubes look greenish/brown as a direct side effect of the dye-the insides are clearly cleaner than the primochill tubing.



This is NOT conclusive proof of anything, but merely my experience & contribution to help solve our tubing problems.
This post just provides a few more variables and their results-i am still hoping to try out the new Primochill tubing in November, and i hope that i get similar positive results with it smile.gif

I am now going to be testing Mayhems UV white pastel with Clearflex 60 clear tubing(as suggested by Mick from Mayhem's), this will remove the silver kill coil as a variant-i am very interested in seeing what the outcome will be.

I have been running primochill di water and red tubing and when i had to change a radiator because of a small leak I noticed a crap ton of this built up. I didn't change tubing but, I am building a complete new watercooling loop with new pumps rads and everything for my 800D

someone please get a sample of the gunk and send it to a cromatography analysis. Determining the composition of it might help deduce the source: If it's the tubing, the fluid, the additive, killcoils, mixed metals in the loop, etc.

I'm no chemist, but I do know that, if you analyse the composition of something in detail, you can deduce by it's basic chemical components how it was formed/obtained.
At least that was the approach that gave the veredict on the EK flaking issue back then (a chemist trying to get to the bottom of the issue).

oh, and please stop throwing blame around. We all know that some rigs represents our e-pen0r, pride or however we call it, but throwing blame around withou any scientific/conclusive basis to do so won't solve the problem, won't open the manufacturer's eyes to a possible issue and won't help the other end-users looking for a quality product for their rigs.

BTW, I just got 5 feet of primochill tubing and then I stumbled on this thread. I'm worried, yes, but I want PROOF that I just wasted my money or not, and if I did, I might go bananas and start using stainless stell braided tubing or actual aeroquip hoses...

well, I can assure you it's the tubing itself, because in 2-3 weeks it was already visible (from new tubing installation), now running a different new tubing and zero problems in a month while ALL components are exactly same and I do use a silver kill coil and have copper+brass+nickel+chrome in the loop.
does it really matter what the substance is? just stay away from poor quality tubing (or ex-quality tubing which is bad nowadays like Primochill Primoflex is).

I still should have a piece of tainted primoflex tubing in the drawer, can mail it out to somebody for testing if interested.

that would be nice, at least we could be sure once and for all about what the hell is that white gunk (that's the curious bastard in me asking questions).

As for the tubing, I might test the primochill suff and see what happens. I don't use a killcoil in my loop and I can get ultrapure water easily at the lab, maybe it'll work. If not, then f*ck this *****, I'm going with stainless steel tubing or something ph34r-smiley.gif

^LOL! I hear ya man, would like to know for certain too, but am no chemist.

stainless steel tubing, eh? kinda stiff a bit if you ask me he he biggrin.gif

Feser UV active is working fine for me now. if you like clear then go with Duralene, lots of people likes it and no complaints so far.

Want proof, use the tubing, you might luck out you might not. Some takes longer than others to start, mine took about 3 months to start then over a months time it went fast.

Same here-just PM me your address and ill send you a small piece(in fact i can also send a piece of Feser tubing so there may be some sort of comparison), but i will want verification/proof of where it will be tested, for obvious reasons thumb.gif no time wasters please.

Look in this thread some where about a month ago or more, and you will see a copy of the letter from Promochill saying that they are aware of the problem their tubing has-what more proof do you need vis a vis Primochill tubing-nvm their damage control post afterwards. wink.gif

Better with copper tubing, as long as your going "all the way" with same metals in the loop. copper and stainless is still an adventure:rolleyes:

just kidding about the metal thing... but yeah, Duralene is the way then. I just got my tubing a month ago, I'm just praying it won't gunk up from just ultrapure water, otherwiser I'll get the Duralene.
about copper tubing, I would only go for that if the intented result was something like this:

That would probably solve any and every possible issue of gunk-forming in the loop thumb.gif
