Plasticizer leach?

What don't you like about the primochill LRT? That's what I've been using in my main rig.

Did you miss the picture in the first post of this thread? I'd also check out: http://www.overclock.net/t/1199158/p...ussion-gallery

Ya the pictures in that make my almost 4 year old masterclear that I just replaced look pretty good. Wish I would have seen that thread before i redid my loop

OK, see the time stamp of my post? 1:36 AM? Yeah, I wasn't really awake. That's my excuse

I alwais had Primochill LRT black and red tubing. The only thing i noticed was a little white deposit on the plexy reservoir and this is after 1.5yrs of running. Tubing was still clear(black) inside.

Sounds like you got lucky. It's fairly well known at this point that there ARE leaching issues with PrimoChill. All I had in my loop was distilled water and it happened in less than a couple of weeks. Same issue with a second batch l ordered.

I haven't bought LRT in umm, almost 2 years. Still clear. Still using it. Something changed.

It could and probably does have something to due with how they manufacturer it. Either way I'm staying away from it. It's 100% plasticizer free for me from now on.

It's only the more recent batches of their tubing having these plasticizer issues, they seem to have changed their formula.

This makes me worried about my loop now since the tubing is only a few months old

My wife's Primochill tubing has turned blackish-brown (was green) and brittle. No more Primochill tubing in this house. Then again. I'm going hardlines (if I can ever find blasted metric tubing) but I think I'm getting her something like Tygon. Not sure yet.

[Sparky]

Well crud. I went to colored tubing to avoid issues with dyes. Now I'm going to have trouble with the tubing.

Not all Tygon is plasticizer free. Read through this entire thread to see my posts.

Same. I have a post in that OCN thread with my 2 week old black Primochill looking like the picture in the OP. I did weeks of reading before buying anything, and it was almost unanimous to not use dyes, and if you wanted color, to use colored tubing. I have some masterkleer in the loop as well that is still clear. Something is very wrong with Primochill if it goes to sh** after two weeks

[Sparky]

Well I'll be taking some stuff of my loop apart to upgrade a bit when I get my new 7850 or 7950 (not decided yet). If I get the 7850 then hopefully Swiftech will have their sink out for it soon. Tempted to get a 7950 but I'm not sure if it is worth the extra $100 or not. But either way, when I do take stuff apart I'll see how bad it looks I guess.

[D749]

No PrimoChill, no dyes and no silver. All I use now is 100% plasticizer free tubing, distilled water and Nuke-PHN Biocide (not CU).

[squick3n]

I do kind of wonder what role the copper sulfate plays. I'm using silver now but I also am not using any nickel

Most people know to stay away from copper. Silver has been the new "thing" in town for the last few years. I ran a strip of pure silver (99.xx%) in one of my machines without noticeable issue or so I thought. It wasn't until I broke down that system and months later went to use some BP fittings that I noticed corrosion on the fittings. I did some digging and that's when I found that nickel and silver can cause issues. Ek experienced this first hand. That's why I don't mess with any of that crap now - no dyes, no plasticizer, no silver and no copper.

That's the thing though. There are so many people who swear and swear and swear that the Mayhems stuff causes no problems. With WC having been around so long it seems strange there isn't a more clear list of best practices

Sorry to break it to you but you have copper all throughout your loop

In my experience silver works great and has no real negative side effects. Do my nickel plated fittings have nickel wear? Yes, but it was wearing off already even before introducing silver to the loop. And it was wearing off all my fittings (I have a mix of Dtek, EK, Bitspower). I ran silver in my other loop for 1.5 years and the nickel plated fittings there didn't look any worse than any other fittings of mine. Actually they were better since they were newer so they hadn't had as much time to wear yet.

I personally believe nickel plating is much more hassle than it is worth. If I could get brass fittings without the nickel I'd gladly do that.

[Kayin]

I still find it odd that EK is the only one having that problem, and especially out in the wider world nickel plating is considered near indestructible. If I had to make a guess, the nickel we're getting is no more than a flash coat, and proper plating practices are not being followed. Take it to any machine shop and get it nickel plated, and I'll bet you you would have to get a die grinder to get it off. Maybe we should push for hard chrome.

Whats up with nickel plating anyway ? Its cool because its shiny?

On another note - can you bend norprene using hot water to make exact bends ?

[tiborrr]

@Muskel: I couldn't. I run norprene in my daily setup but that bugger required some hefty curves to avoid kinking

There's no non-metal WC tubing, including Norprene, that I haven't been able to bend with boiling water. Heat it for a few seconds, straighten it out by hand and then keep it submerged in ice water for a few seconds. Repeat a couple times and I've been able to bend the tubing however I like. Just remember to get it in place before it completely cools.

This is one of the things that has endeared me to this tubing. Using a long spring to hold the inside shape, I can bend the Norprene to an extreme shape, alternate it between boiling water and ice water a few times holding it in each for a couple of minutes, and it will hold very tight bend radii without kinking or putting stress on the barbs.
