Thermaltake Pacific Black 4 Build-In O-Rings C-ProG1/4 PETG 16mm OD Compression Fitting CL-W214-CU00BL-A

I prefer using these over the original compression fittings for Thermaltake's PETG lines. They're easier to use. They allow for a slight variance in tube fitting to butt; meaning it doesn't have to be perfectly aligned to get a 100% no-leak seal on the line. This is due to these fittings have 3 o-rings over the 1 (I think it's one on the old ones) and 1 additional o-ring for the connector outer too that screws down into the rest of this. These are 3 piece compression fittings. You have a base (what I'm calling the butt) that screws into the socket (standard 1/4" fitting), then a 'fitted' center ring that has the 3-o-rings in it that fits over the end of the line, and then the screw on fitting that has an additional o-ring for the 'top' of the ring with the other o-rings inside it. So a 4 o-ring system not including the other standard seals too.The tool could use some reworking. Sometimes it works flawlessly, sometimes it's a struggle because it WILL slip out of the notching. Maybe Thermaltake can take a NOTE here and add some rubberized 'feet' that are on those notches to make it maybe not SLIP OUT of the notching when you're tightening the base down.Overall I'd buy more again. Sometimes I get them to replace where I've had to use pliers to take the fittings off after a year of pressure and other factors that won't let them loosen back up so they get a little stripped of color. Or, sometimes I need more because different loop idea requiring more turns, joints, etc.Recommended if you don't want to use the old ones or if you want a nearly 100% guarantee that these seals won't leak. Mine NEVER have unless it was user error and there was this one time I flooded my GPU...thankfully it did not damage that...whew.Pics attached of how the fittings look in a loop. Cheers!

Before I get started with the exhaustive review, here's my two cent version. The fittings are difficult to install due to the wires, the pipes can come loose, and the overall effectiveness of the LED's is extremely disappointing. I simply cannot recommend this product to anyone else.I really had high hopes for these compression fittings and RGB lighting, but upon completing this build I've decided these just aren't worth the money. At this point, I'm not sure what possible good things I can actually say about these fittings.First, let's start with the fittings themselves. These fittings, unlike most other fittings you have probably used, have a barb in the middle with two small o-rings stacked on top of one another. You absolutely have to chamfer the inside of the pipe or you'll never be able to get the pipe over them. Once you have done so, good luck trying to get it on anyway. About half the time, even after wetting the o-rings and inside pipe, the second o-ring will undoubtedly get pinched or pull out of it's groove, shoving it against the LED's in part, or entirely. IF that happens, you have to start all over or find a small plastic pry tool and gently try to shove the o-ring back inside. Once that's done, I found that 2 of them just wouldn't stay on properly, and the pipe kept creeping off. To fix that I wrapped teflon tape around the bottom of the pipe so I could tighten on the top of the fitting and keep the pipe from popping off.Next, let's talk about the LED component. The LED component is a ring of small LED's that sit just under the the edge of your pipe. They basically illuminate the circumference of your pipe. The LED's themselves are completely unprotected against water, even a small drop. If you have a few drops of water on them when you turn on the system, "poof" goes the LED. For this much money, I would have expected that they encase the LED board, and put some sort of coating or clear sealed cover over them to prevent that, but alas they did not. The next issue is the wires, which others here have pointed out. They are indeed attached to the ring in a very flimsy manner. My suggestion Thermaltake (if you are listening), is to use a small bit of clear glue to cover the solder points, to prevent that tiny fragile wire from breaking off when you are trying to tighten your fitting. If you are not insanely careful, and even if you are, likely you will break or bend one of the wires too much, and that one is toast unless you are handy with a solder gun and are able to repair it. After finally assembling and getting the system up and running, I found that the LED's were mostly innefective, unless on extremely short runs of pipe. The other LED's on my RTX water block and reservoir completely over power them.Last, let's talk about the controller. Again, I had high hopes, but again misplaced. The controller looks nice, but it comes with velcro to attach inside your case. My razer chroma controller has 2.5" mount points, so I am able to place it where any drive can be installed in my case. The biggest issue is the looseness of the connections. I found that you have to fasten your cables close to the unit, otherwise the weight of the LED cables will undoubtedly pull them out from the controller. The software, well, it's extremely underwhelming when compared to Razer synapse. Fortunately, it is actually chroma compatible, so I am able to modify the LED colors and effects through Synapse and just not fiddle with the TT software at all.

I wasn't going to do RGB for the pump and fittings, just due to the fact that I was going to use colored coolantBut since the pump/reservoir was only $20 more than the lower model, I went with the P32 D-5, which has an excellent, mostly clear cap that you can rotate the intake holes to make it easier to fit the hard tubing. So I had to get the RGB fittings, because once you're in - you're in fully!! You'd wind up with a whole lot of controllers, but the RGB on Thermaltake is really good and their 120/140 quad fans are the best out there. I alsothink the TT plus and Neon Maker software are better than motherboard software like Fusion 2.0 (what I have). Lots of wire to hide with these fittings, but you can control them and the pump (and the water block, I got the MX1 Plus - awesome, bet looking one, imo - and it tells temperature.) If you go RGB pump, then get the P32, rather than the P22 plus - both RGB but the cap is MUCH better, for $20 - and also get the RGB fittings, they are all worth it. I have there products that work with Thermaltake RGB plus software:4x 120 mm quad fans1 - MX1 Plus RGB Water Block1 - P32 D-5 RGB Pump/reservoir1 - irgb 1000w PSU RGS (syncs to TT Plus software).Pic included is dark so you can see the RGB. Just got the fittings today, have not had time to put on yet.6x RGB fittings (enough for a complete loop from out radiator to back in radiator.I don't have their RGB RAM, but it's out there - with water cooling. I don't like mixing parts in a build, mine is all Thermaltake w/ Gigabyte Vision D Motherboard and a Gigabyte GeForce 1660 Super GPU. All in all, I highly suggest Thermaltake.Now please get me a Core P7!!!!!! I need that.....very much!

Very easy and versatile.

Honestly quality fittings fun to build with makes it so much easier that you can measure it flush without having to compensate for anything. Solid fittings, worth the extra $60 CAD over other fittings. If you look at how much you spend for a while water cooling build, these are worth it 100%, I hate Corsair and I am totally becoming a Thermaltake fan boy, currently they are doing everything right, and their affordable copper 64 mm radiator, good job Thermaltake.Full install review:I've seen people complain of leaks, for sure due to human error. I have noticed that these fittings are not forgiving if your tube is pushing out at an angle if your tubes are not well lined up as other fittings can be. Anyways if your fittings are pushing at enough of an angle even with other fittings you'd end up with a bad leak eventually. I find these were perfect and made it very easy for me to get perfect bends. If well used they make everything so much easier and are worth every penny.UPDATE: 2.5 weeks of use now still no problem, no leaks and everything runs smooth.

Bought these due to running out of the EK torque fittings. Is says petg on the add but they work awesome on acrylic tube as well. No leaks and easy to install. Only downfall is they scratch very easily so be careful when installing

These fittings are not only easy to use, but hold up very well against leakage. I even tested them by using tubing at about a 15 degree angle from the fitting. It is noticeably crooked and tight, yet after a year the fitting (or any others in the system) leaked. I have reused them several times with no issue.

Very nice fittings nice and hefty premium feel to it. I tried a few other fittings like bitspower and although bitspower are a big brand-name I went back to thermaltake because the bitspower fitting were a lot smaller that the fittings I already had and just didn't look right.

RGB to the friggen MAX
