PrimoChill PrimoFlex LRT Custom Watercooling Flexible Tubing -1/2in.ID x 3/4in.OD, 10 feet Bundled with System Prep and Coolant, Made with Premium Materials, Proudly Made in The USA - Crystal Clear

Absolutely excellent tubing. I've been into building custom water cooling systems for years and this is by far the best tubing I've seen or used yet. Great tubing. Perfectly clear with no labeling, very flexible, comes with coolant system treatment and flush. It's a bit on the pricey side, but i'm sold on this tubing. I'll never use anything else again unless by some miracle I can find something that's actually better than this.I’ve gone through at least 3 boxes of the clear and one of the black. Sections of the clear have been in continuous use for about 5 years, still seems fine, although a little cloudy. I only service my loops every 2 to 3 years, the benefit of running strictly quality coolant rather than water. The black tubing isn’t as flexible as the clear, but it looks really cool and was cheaper at the time. I prefer the clear because it’s easier to determine if there’s a problem with the coolant. Actually, the black may be a bit oversize on the OD (outer diameter), I tried to use compression fittings and I had to modify them to fit, and ended up just using barbs and hose clamps in the end, which are safer in my opinion, not to mention considerably cheaper if you don’t mind the look of them. Aside from the pics I post online, nobody sees my loops but me, so I don’t put too much effort into some things.The first pic isGigabyte Z270x Gaming 9i7 7700K Koolance CPU390 blockSLI EVGA GTX 1080 Ti Hydrocopper32 GB DDR4 3466 G Skill TridentEVGA P2 1600 watt PSUThermalTake W200 tower1 x Koolance 240x55mm rad1x Phobya 280x60mm rad2 x Alphacool Nexxos Monsta 480x90mm rads2 x Koolance 770 ml reservoirs2 x Koolance PMP450S 24v D5 pumpsKoolance LIQ705 coolant2nd picEVGA Z390 Darki9 9900K with Koolance CPU400 blockSLI Nvidia RTX 2080 Ti FE with EK Vektor blocks32 GB DDR4 4000 G Skill Trident(The rest same specs)3rd picZ390 Dark/9900K/32 GB DDR4 4000Thermalrite 240mm AIODell RTX 3080 with Alphacool EisblockCorsair RM1000x psuFreezemod 360x25mm radFreezemod pump reservoir combo4th picGigabyte z790 Aorus Masteri9 13900K with EK Velocity232 GB DDR5 7200 G Skill TridentMSI RTX 4090 Gaming X Trio with EK Vektor2(Rest of specs the same)

Dipping my toes into custom water cooling for my rig was an exciting yet daunting task. PrimoChill's PrimoFlex LRT tubing played a significant role in making the journey smoother. Here's my experience:- Flexibility: True to its name, this tubing is genuinely flexible, making it easier to navigate around the tight corners of my build. Less stress on the fittings means a reduced risk of leaks.- Clarity: The tubing is crystal clear, showcasing the coolant's color. Over time, I've noticed no discoloration, clouding, or any plasticizer build-up.- Size: The 1/2in.ID x 3/4in.OD provides a balanced flow for my system. However, if you're new to custom loops, ensure you get matching fittings!- Durability: While the tubing is sturdy, I did face a bit of kinking in some tighter bends. Not a deal-breaker, but something to keep in mind.Final Thoughts: For someone delving into custom watercooling, PrimoChill's PrimoFlex LRT is a reliable option. Though not without its challenges, its flexibility and clarity make it worth considering for your loop. Happy cooling!

Nice and thick. And the added cheese are a big help.

I have had this before very good quality, and it lasts a long time.

Works great for my full open loop, nice thick tubing looks closer to hard-line than you'd expect without all the horrible maintenance issues that would come with it. Hard to kink for soft-tubing and cuts nice and clean, included liquid utopia works well. Haven't used the system prep as I had already prepped all components before this arrives but it's a nice bonus.

Have used these tubes for years, and found them again.They stay fresh, and not any plastisizer issues for my loop

I installed this in my system over 6 months ago when I had got a leak in my old reservoir and decided to rebuild the loop with larger tubing. So far it's worked great, it has a very thick outer wall which really helps prevent kinking. I'd much rather prefer larger bends and less flexibility over the possibility of a system-damaging kink at some point (have had cheaper tubing do this before). Another, and possibly the best feature, of this specific tubing is it has not discolored yet! I usually use UV blue coolant/water, and a clear tube. However I've never had a tube stay clear for over 6months before. They all turn a greenish color. This has not yet! I don't use any additional treatments or copper or anything (although I probably will start next time I do anything). I definitely recommend this for keeping a good/cleaning looking system a longer period of time

Tubing is great, the flush and cooling concentrate you get is a bonus. Totally 100% worth the price. Running for 30 days without a sign of issue in my loop, I will update this review if that changes

Tuyaux de très bonne qualité et facile à installé.
