Potential issue : EK-DURACLEAR TUBING 16/10 - CLEAR

Using this for a new loop i'm putting together, and in the process of leak testing i have encountered an issue with clouding after a matter of hours.

https://www.overclockers.co.uk/ek-water-blocks-ek-duraclear-tubing-16-10-clear-3m-wc-9dc-ek.html

Rig was left to run for 24hours to leak test and after that period the tubing was a terrible cloudy colour, so decided to test outside the loop to rule out and contaminants from the radiators etc.

Cut 3 small lengths of tubing and placed each one in ;

EK-CRYOFUEL CLEAR
MAYHEMS ULTRA PURE H2O
TAP WATER

After approx 24 hours, this is the result ;

all 3 samples had clouded.

To rule out that the exposed edges of the tubing caused it ( even though my leak test had clouded in normal useage ), i did a second test using a couple of fittings.

This is it after approx 18 hours - EK tubing with EK Cryo liquid

and here with a piece of unused EK tubing for comparison

Clearly ( pardon the pun ) an issue with the tubing in my opinion.

Anyone alse using this ?

This happened to me I made a thread on it. OCUK gave me more tubing but it ends up happening to all soft clear tubing and coolants with gylcol in are worse.

I think you just have to run neat distilled water if you want tubing to remain clear for longer.

Seen it happen with nearly every clear soft tube ive had with many brands and many different coolants. Result was that they go cloudy after some period of time. hard to solve. In the end I just went to zmt to save the faff, far better IMO.

I've had better results with Mayhems but it's a problem with all plastic tubing and it has been since pre-mix came into fashion. Was less of a problem with distilled and pt-nuke.

Tried some Mayhems clear tubing, exactly the same result - clouding in less than 24 hours ( not in a loop, just tubing and fluid ).

Not willing to throw any more time or money at testing tubing, so gone for EK ZMT.

I'd agree with that. I've got some Primoflex Advanced LRT that my emails say I bought in 2015. Been running with distilled and PT Nuke since some time after that and probably not cleaned out/flushed as often as it should be, and it's still clear. Did have bad clouding with the Tygon tubing I was using prior to that though.
