I ran across this thread searching watercooling information and joined the group to hopefully answer your question on the plasticizer leaching. According to my coworker who has over 30 years of chemical technology lab experience, if plasticizer is used in any flexible tubing it will eventually leach. The amount of plasticizer used varies between manufacturers and batches. The common factor is leaching is directly proportional to temperature. The higher your loop temperatures, the quicker the leaching.

I have see the same thing last summer. I ask to a technician if he know something about the leaching or whatever. He know the issue since they use alot of tygon tubing every where and his solution was to change the tubing every years....

Thank you both for contributing. While it is very much appreciated we have this information. Primochill stated that it leaches at approximately 30c. So if you're not doing much on your system, at Idle it should never reach that mark. Or at least not if you aren't Overclocking.

But what's the point of watercooling if your system is at constant idle? For 10c difference in idle temp? Seems to me that is costly and pointless. I water cool because my Mainboard requires a cooler temp than on Air and because I Fold. So my system is NEVER at Idle. My average temp is approximately 39c at Load. Also there have been owners(this thread is chock full of instances) people whose tubing didn't last a week before the plasticizer started leaching out of the tubing.

Haven't heard anyone complaining about the Duralene tubing though. Really wish they made white tubing. thinking.gif

That's where I'm kind of stuck. My primochill is less than a week old and showing signs of leaching, I don't want plain clear tubing, and I have 7/16 x 5/8 compressions so I can use feser. This new primochill better be good, even though I feel like I should get it for free seeing as the last tubing I bought from them didn't even stay clear a week.

I haven't read this whole thread but I thought I would share this.

This same thing is happening to me, I just set this loop up 2 weeks ago, in this pic you can see where I pinched the tubing and it rubbed off on the inside, notice the dark spots, when I shine a flashlight under those spots the tubing is clear and the rest looks clouded.

you all still using Primo should write complains to them, so the allmighty Brain could respond to your issue from his pedestal and maybe finally recalculate his % number of issues among all sold ... so far the dude states the problem is limited only to 5% of owners and offers some BS Sys Scrubber solution from a good heart (might work or might make things worse as it did for me), but at same time publicly denies the problem ever existed AND at same time announces the launch (in November) of NEW Primochill tubing as free of any issues LOL! sounds like schizophrenia to me ... I persoanlly ditched that tubing and forgot about that psycho PR rep guy and went with other brand, no more trouble.

THIS (especially the bold parts)

Only one small addition mate-in hot countries(or in your case hotter states) we have a higher idling temp due to higher ambient temp-so that means leeching from the get go if leeching occurs @ 30c. So we are back to square one-faulty tubing mad.gif

That's why I only use Tygon R6012 (Norprene) and nothing else. Granted it is not the prettiest but you can always sleeve it up thumb.gif. This is what I always recommend our customers, go with Norprene.

I believe dye breakdowns have been a scapegoat for far too long, I believe the majority of problems come from leeched plasticizer that has been dyed by the colour of the coolant.
