Discolored tubing

post #1 of 7
Thread Starter 
So I put together a loop with the XSPC RX360 kit about two weeks ago and used the silver kill coil and tubing that was included with the kit. Today I added a GPU block and used Durelene tubing. I noticed the XSPC tubing had a significant yellow discoloring (compared it to some unused tubing) and my silver kill coil had a yellow tint. I'm afraid to put the kill coil back into the loop for it to mess up my Durelene. Anyone know what might be happening?

Edit: I'm using distilled water and copper block if that helps.

If I remember right that tubing is known to do that and just isn't very good all around. I'd definitely recommend using some quality tubing in the whole loop. The discoloring most likely isn't anything bad growing in your system or anything like that. It's just sub-par quality tubing.

Yes, I have already redone the whole loop with durelene tubing but I don't know if I should put the ... "tarnished" (It has a yellow tint) silver kill coil back in the loop or buy a new one / biocide. Also, thanks for the info, good thing it isn't the block or anything.

Did you by any chance flush your radiator before you used it for the first time?

Yes, about 6 full rinses.

Yeah, it is just the fact that the tubing is crappy to begin with then. As for putting the kill coil back in, you could clean it up a bit if you can and put it back in. I don't think it would cause you any major issues. As far as I know, the silver will "tarnish" because of being in the loop with copper/it not being 100% pure silver. Most kill coils are about 99%-99.99% silver. Since they are "impure", they can react and tarnish a bit when exposed in a loop. There is usually also some oxygen in your loop (air bubbles etc can still be in there), which is an oxidizer. This can cause some oxidation on your silver as well. I don't think it is anything to worry about, and I'm pretty sure it would still be effective. Hopefully someone with maybe a bit more knowledge with them will chime in. I use Mayhems (which has biocides in it already), or just biocide drops when using distilled. Good luck. thumb.gif

So update:

I replaced the crappy XSPC tubing with some crystal clear Durelene, and the Durelene also began to tint the same dirty brown color as the original tubing in about 2 weeks. I'm buying some more Durelene to replace the stuff that has turned opaque, should I take the kill coil out as well and just try some biocied?
