Ok, so here is a photo of what i plan to be testing over the next few months, and a photo of the Feser that i had been testing in a rig:
Top left : (L->R) is Clearflex 60 clear tubing, next to it is Masteecleer clear tubing which is being used as we speak with Mayhem's UV white pastel (im nearly finished with my wifes rig so photos will be posted then-ive been using the Masteecleer for 3 days)
Top right: 17ft of Primochill Advanced-i just got it today, my personal thanks to Primochill for replacing the LRT tubing i had been using before, and for posting the replacement out here to me in Europe-kudos
Bottom left: 6 month+ used Feser UV Clear tubing-i had been running Mayhem's red dye, WFI water (water for injections-its purer than Distilled water, and NOT to be confused with saline solution), 2 drops of Mayhem's extreme (biocide)and a SKC.
There is obvious heavy staining(Red and Pink dyes are the worst for staining), but no heavy 'cream cheese' deposits. I run my rigs 24/7 (i am not exaggerating
), and the average temp is between 27-30 celcius (this goes up to 42c max whilst gaming and under load etc).
One final note: the Feser tubing that i had been using was stiffer than the average tubing i had used in the past ie:the Primochill LRT, and now after 6 months it is even stiffer.
The more PVC in tubing the more pliable it is, and it is PVC leeching which is the 'cream cheese' plasticizer build up that we encounter.
Again please refer to this link for more info-you can also read the whole of the recently released study if you have a look on the page ive linked, but it will cost you-it makes things much clearer
So im taking an educated guess that the new Primochill Advanced tubing has less PVC in it because it is stiffer than the LRT, but i am not 100% sure so DONT
quote me on that (Primochill feedback would be helpfull here
I will post photos of used tubing as and when it is available-i plan on running the Primochill in another rig i have running atm.
Hope this has helped a bit.
