SDTC Tech4-Pack G1/4" 5mm Male to Male Connector with Sealed O-Ring for PC Water Cooling Systems Extender Fitting

As i suspected for the past 5y, almost all the fittings/connectors are generic and just get the different brnads stamped on.Problem is that the clones seem to be what didn't pass QC at the name brands (primochill/alphacool/xspc/bitspower..),as 100% of the 20 (clones) i bought (to rebuild my loop) had incomplete plating/paint.This will be a problem if you have a proper cpu/gpu block, as they are usually copper, so with fittings made from brass or alu, your introducing a 2nd metal, which can cause corrosion.So only recommend them if you use some form of corrosion inhibitor made for pc cooling.Automotive stuff is either coming with things you don't want in a loop, are not preventing bio grows, and most will reduce cooling performance, as temps are different.

As you all know, fittings are freaking expensive. With these, you get 4 male to male fittings for just 12 bucks. I have all corsair fittings and they are a perfect match.

wish i could find longer male to male G1/4 on amazon but i had to go with this cause the real water cooling website cost so much just to ship one part

Overall quality is good. Made of brass. Orings seem cheap but the work. Finish is nice. The black closely matches corsair black.

14 yr old first liquid cooled pc build. Much easier to cleanly fit the hard lines.

Trash. Leaks and is shoddy. Save your money and stick with reputable brands

With all due respect, if these fittings are leaking, I'd check my tubing and see if I'm overextending the tube and it is not precisely perpendicular. Leaking from fittings can be a result of tube being stressed and not exactly formulated.

Great and goodWork fine with me, everything ok
