SDTC Tech 4-Pack G1/4" Male to Female Extender Connector 90° Rotary Elbow Enhance Multi-Link Adapter Fitting for PC Water Cooling System, Silver

90 degree fittings for liquid cooling. They fit fine, knurling helps you get them seated properly. I have bought, and will buy them again. Quality seems on point, no leaks, and have held up to some weird system builds.

I was not ready for how well these where built. I was changing the colors in my PC to have a darker look, to tone down the unicorn vomit. I went with the black hardline tubing from Corsair, this made me want to have a more matching fittings. I bought these a way to save money on fittings that would not be seen, in case they looked terrible. But I got them and they looked great. even better was the fact that they work so well. The seals are great and the movment for the rotary was better then other brand names, looking at you corsair/ekwb. I am sure they are made in the same place but still. These have what I need looks and performance without the insane price.

I bought bunch of SDTC fittings when I first started water cooling my dell RTX 3090, thinking the price was good to try it, if it doesn't work out, I can always switch to other brands. To my surprise, fittings from SDTC worked pretty well. it is easy to tighten and looks nice and shiny. About the only complain that I have was using a plyer to give the final little tightening may scrap some of the shine, so the surface is probably a little soft (easier on the hand grip when tightening, I guess). Otherwise, it has never leaked in the rig. Good product.

Great rotary 90° fittings. No leaks, just make sure if you are using compression fittings, if you're fitting already has an O-ring, you don't need to put the one in the bag on.

I've had these for a few months, and waited until I had given them time to compare to my other fittings. Not a single leak from any of them, however I have noticed that there are shiny flakes building up in one of my tubes. I don't know if this is from my waterblocks on GPU & CPU, but they did not appear until after I added these fittings to my loop and I don't see anything signs of wear on the blocks. I'm fairly certain it is the chrome plating on the inside of these, but I am not concerned that it will affect any components in my loop.

Very good quality and materials, competitive price. Fitment is excellent. Works well in my pc cooling loop.

I used these along with some 45* elbows to get my lines out and around my radiator and tank. Although they are expensive, they do the job well. Steampunk/Dieselpunk wall mounted PC is all liquid done, and so far, no leaks (been running pre-conditioner for about 24 hours so far).

Initially I had an external heater core as a radiator running to a pump and to my 3080 ti. I had my i7-13700k (who knows how long it will last due to Intel's problems) connected to an AIO. I decided to have everything into a single loop so I removed the AIO, added a 360mm radiator for the additional load and a water block. These fittings were used along with some soft hose compression fittings to make one large custom inter/external hybrid loop.
