PrimoChill1/2in. Rigid RevolverSX Series Fitting - 12 Pack - Candy Purple

I have been doing my own custom loops for over a decade now, and this was the first time using the RSX fittings. Immediately I could tell these were miles better than any other fittings on the market. The sealing mechanism is dead simple, very forgiving, and almost idiot proof.Now let me say that I am not an expert at rigid tube bending: my cuts are not square, my bends are off and you can see the areas where i had to use sandpaper on the ends of the tube. My tubing looks good enough once assembled, but you can see the flaws of my workmanship in the details.But here is the great part: these RSX fittings don't care how rough your tubing is, how poorly it was cut, or if you have to coerce your tubing into the right shape with a bit of force. They just work. everything seals great with no leaks. I have been running this loop for a week now, and everything is perfect.as for useability: when you install the RSX fitting base, do it first before you install your blocks or pump. there is no place to get a good grip on the base, and you need to get them almost as tight as you can by hand. not ultra-tight, just a pretty good hand tight. once the base is installed on your pump/block/etc, then assemble your components into the case.once you have your tubing bent and are ready to finish the loop, the screw caps only need to be snug. install the tubing, make sure it seats into the fitting base (it will be obvious how it sits in), and then finger-tighten the caps. a little snug is all it takes to seal the o-ring. you will be tempted to over-tighten the caps but don't do it.that's it!last tip: the fittings are large, so make sure you have clearance. there is 1mm of gap between them on my EK velocity cpu block. close, but enough to work with.

These fittings are pretty awesome, used with primochill 1/2 petg. Just cut the tube and prethread the collar then the o-ring, push flush into the fitting then hand tighten. Provides a serious grip and have not had a single leak that wasn't caused by user error. The provided tool is for removal of the collar, not tightening. After a few turns the compression seals the collar and o-ring quite secure, to the point that you aren't pulling them out. The powder coat is well done and sturdy, after a month or so still no flaking or residue on fingers. Also the collars are interchangeable, amazon doesn't sell just the collars but are a quick trip to primochill.com and you can find every color that they carry there. Instead of buying a new set I suggest grabbing about 24 of these then just grabbing the collar replacements from there. 24 may seem like a lot but once you get into watercoolong it would behoove you tto always keep some spares for bigger more complicated loop setups. Overall nothing really negative to speak of about these. Only word of guidance would be to take into account the full fitting width when loop planning to account for the thickness, make sure you have the space to turn them and to be gentle if/when using tools to not ruin that primo powder coat.

I was worried about the color and how it would turn out. But this is such a piercing red it's exactly what I wantedThe fittings all seat well and the tools are cool. They sort of serve as torque wrenches bending when you've added enough force. Nothing leaks. Everything's easy to use. I'm glad I bought themAnd they're not as bulky as you would think. One of my concerns between these and monsoon was the possibility of them seating like big round doughnuts on the tubes. Not the case at all. See images below

Good quality, no leaks. The green really stand out on my rig and I love them! Only one downside would be that some were tight on the base coming out of the package. I would recommend using a leather glove to crank them open as I easily sliced my finger up doing so.

The media could not be loaded. So far not a single leak out of the fittings as long as they are installed properly.Only thing you need to consider is the size of them they are pretty big and I had to scrap the other fittings I thought I could use to mount these onto.Ended up just mounting directly on the water blocks.

Presentation wise they look amazing! Mine came with 2 sour patch kid candies which was a little weird but no worries. I also received them 6 days before they were supposed to arrive!DISCLAIMER: I didn’t eat the candy because I don’t trust packages with food in them but it was a nice gesture. 😂

Thank you Primochill for giving me a huge reason to never but your products again.The design of these caps is incomprehensibly horrible. They are designed in such a way that you must screw in the fittings before getting able to get the caps off. Don't screw in the fittings hard enough and the entire assembly comes off. Screw them in just a tad too hard and you're never getting the fittings off again and there is no tolerance between the "sweet spot" and "too hard".Now I have a crappy fitting welded to one of my radiators. I can return neither product because desperately trying to get the fitting off has damaged it beyond the point of getting able to return it. All in these fittings have cost be about $150 to get NOTHING in return.I highly recommend this product if you're a sadomasochist. I really hope I can get these awful fittings off the rest of my gear, I haven't even tried yet.Thanks a lot, Primochill!

Great product

Really wanted to give these a good review but really can't. The fittings are brilliant, well made great design and the colour is perfect. But it's all let down by the tightening tool which snapped on the first fitting so I had to use grips to tighten them and ruined all the paint work. Gutted but least they are physically doing there job
