Thermaltake Pacific Black 4 Build-In O-Rings C-Pro G1/4 PETG 16mm OD Compression Fitting 6 Pack CL-W214-CU00BL-B

Worked great and great quality! To people talking about these leaking, make sure everything is completely straight in the fitting while leak testing. It's not the fittings. It's more about your pipes being straight. I did a leak test(everything is unpowered but the pump), one fitting had a little leak. Turned it off, had paper towels out, so no issue. Noticed the pipe wasn't completely straight. Adjusted it a little bit and then not a drop out of it. So just make sure everything is straight and you'll be good to go.

I don’t usually post reviews but these fittings are amazing. No leaks for me. PAY ATTENTION TO THE MIDDLE RINGS. THERES A SPECIFIC WAY YOU NEED TO PUT IT SO THAT IT SEALS WITH THE BOTTOM ORING. Cutting the tubes to length is not a guesswork anymore. That’s why I love them. Plus they look good

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!

Great custom water loop fittings never leaked I've done three custom water loop PCs

not a problem with these fittings, no leaks, easy to use, matched my computer great with the black and slight white line on it, Thermaltake is one of my favorite computer accessory company too!

They are not bad at all, however... they are a bit large to the point I cant put them on things like the outlet to my D5 pump, so I had to quicky bug a buddy for an male-to-female extender. Other than that not bad. (SIDE NOTE FOR PEOPLE LOOKING TO BUY: Some of them are very (and when I say very that is more like very on overclock) hard to open when you first buy them. Some I had to use tools to get apart)

A little pricey but the quality is so much better than other products I’ve tried. They are colored in a high quality way. The pieces slide smoothly on the tube without scratching it which is nice and the threads are super smooth. The 3 piece design is much better than two piece because it gives you the spot where the tube hits so it makes it really easy to measure for tube cutting. These are a great product and will definitely use again in my next build.

High quality build, durable design, good compression on rough ended tubes. Easy on the fingers. "You've purchased this item 3 times"

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.

pro: es un producto de calidad, el empaque es bueno y protege el producto de golpes tiene un excelente agarre y su instalación es muy fácil.

Can't really put a price on liquid cooling leaks. They can be very destructive and if you go cheap on your cooling loops, you will pay for it eventually with damaged components, or worse. I put these on my first rigid tubing rig, and haven't had one leak in over a year of use! Worked so well I bought some more for when I decide to re-config the loop. Overall - quality connectors, and I wouldn't buy anything else.

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

Buen producto, dudo que otra marca lo supere, aunque el precio es un poco elevado
