PrimoChillPrimoFlex LRT Custom Watercooling Flexible Tubing -3/8in.ID x 5/8in.OD, 10 feet Bundled with System Prep and Coolant, Made with Premium Materials, Proudly Made in the USA - Crystal Clear

This tubing was a perfect replacement for the Tygon tubing I was using and $120 bucks cheaper. Same thick walls, fits the barbs very snugly, and allows excellent flow. Tygon tubing is not supposed to kink when it makes a sharp bend, and this tubing is the same way, very clear and has not clouded in the few months I've been using it. I put the silver coil in the tubing this time (ASIN B00A66HMRC), didn't experience any microbes the last 7 years but the Tygon did cloud, I could clean the inside of the Tygon tubing with a small screwdriver and rag but wasn't going to go through the hassle of doing it to all the tubing, easier to replace with this stuff, and so much cheaper. I like that this product does not have any writing on the tubing, just looks cleaner. Great product, will update if anything changes.

I have been using this tubing for a month now. I see no signs of discoloration or residue.10ft was more than enough for my loop. I have about 3ft leftover.Comes with a bottle of Sys Prep, for pre-treating your loop, and a bottle of Utopia, for anti-algae and anti-corrosion.I used hose clamps on all barbed fittings. Tubing is soft enough to grip and not leak. Yet it's hard enough not to split or rip.I would definitely recommend this to others and will buy this again for my next custom loop!

I've had this tubing in a water cooled system for well over a year now and I love this stuff. It looks great in my NZXT H440 case and does just fine with about every compression fitting I've used it with. I've had zero evidence of failure and the color looks great to this day. I have several tight bends in my system that forced me to take a chance on the "Low Radius Technology" this tubing is so proud of. Well, it seems to work just fine. I highly recommend this tubing for your water cooling build.

I had the clear version of this before, and it was excellent for the ~12 months I had it in my loop. This seems to be just as good quality.HOWEVER, maybe the one I got has been sitting in the box too long, or got wet or something, but some of the dye from the black cardboard leeched into the tubing, discoloring it. It isn’t a huge issue, I just rotated the tube so you can’t see the marks once it’s installed, but still, pretty annoying.

Primo has been doing this the right way for a long timeThere's nothing new or ground breaking it's just good reliable tubingVery clear, no text on the tube, cuts easy, folds well, doesn't kinkWould recommend

This tubing works as expected. It is crystal clear and very solid rubber that won't easily kink. (Yes, it is possible to kink it if you try.) It is 3/8" inner diameter and 5/8" outer that fits connectors from at least 3 different manufactures (I have Alphacool, Thermaltake, and Barrow connectors.) All of these connectors are difficult to get on, but fit. I've been using this tubing for 2.5 yrs now and after upgrading my CPU, I realized it is Slightly cloudy. I use Koolance clear fluid and a silver coil. I will gladly buy more of this tubing in the near future!

The tubing is awesome. Theres a sliiiiiiiight fogging when I use distilled water. But thats normal and doesnt fog up enough to not be clear anymore. Its mostly from the inside of the tubes surface than the water itself. I havent had any issues with the lengths I've bought. Just be sure to measure twice and cut once !

I wish there was an option to buy this without the cleaning agents included. NOTE THAT THIS DOES NOT FIT ON THE BARROW 3/8"-5/8" FITTINGS, even though the description/box says that they are those dimensions. I know it says at the bottom of the description that they might not fit on all fittings, but come on.
