I've been looking for blue tubing on frozencpu.com and what I want is a solid blue tubing that is not transparent. The best I can find is Feser UV blue or PrimoChill LRT UV blue but both of them are slightly transparent; does anyone else have any brand suggestions?
I'd like it to be available in 1/2" ID, 3/4" OD for aesthetic reasons.
That doesn't sound like plasticizer, it sounds like something totally different. I've always noticed cloudiness on my tubing, but I've never seen anything on or in my blocks (ever). I think there has to be other factors in play in these instances, which makes the argument that 'blame plasticizers' is the real issue. I'm also not going to say they don't cause it to some degree, but I've never witnessed it personally...and I've been doing this a long time, with a lot of drains, tear-downs and refills under my belt.
Could be plasticizer, but looks more like tarnish/oxidation from flux or other metals. It's difficult to say, but I'm not going to discredit the claim or argue against it. But no...I haven't seen anything like that on my blocks except the ones that have been sitting in boxes up in my attic for a few years.
