Dracaena 6 Pack G1/4" Thread to 3/8" ID, 5/8" OD Compression Fitting for Soft Tubing, Soft Tube Connectors for Computer Water Cooling System, Black

Quality is pretty good. No issues.

These are the best price of any similar fitting I could find and worked perfectly on my budget watercooled pc build I’d highly recommend them !

The compression fittings feel high-quality and durable with their brass construction and black chrome finish. They provide a leakproof seal with an embedded O-ring. However, tightening them on EK's ZMT Tubing was challenging (I blame EK's tolerances, not these fittings). The minimal packaging (just a plastic bag) could be improved. Despite these issues, I would buy them again.

On first inspection, these watercooling fittings seem well made and have a good level of finish. When inspecting the outside of all six fittings, most of them have a problem with the black coating wearing off where they have been rubbing against each other in bag they are provided in. I would suggest the manufacturer individually shrink wrap the fittings to give them a level of protection during shipping. Assembling the fitting onto a spare piece of tubing was straightforward, they are a tight fit and the locking collar provides good force to ensure there are not any leaks. By hand I was unable to fully seat the collar but this wouldn't cause any leaks. The design of the fitting results in them being a good amount larger than other premium brands (see photos for comparison) but this should not cause any compatibility issues. There is an o-ring pre-installed onto the treaded side and whilst sufficient I would like to see it a slightly larger diameter. In terms of price, they are cheaper than premium brands £4 per fitting compared to £5 per fitting. You will need to decide whether the cost saving is worth the small issues highlighted above.

These do work but whilst tightening these the paint scrapes off, they are okay for the price but if you are wanting something that lasts, I would spend a bit more money and get something a bit more premium

Not compression fittingsSurprised people are happy with these. They have only a push fit for the hose. They have a nice cover but this does not apply compression. The O ring does nothing. There should be splayed “fingers” that fit on the outside of the tubing that get compressed when the outer collar is tightened, same as any garden hose connector. I could simply pull the hose off after fully “tightening”. Will be returning

These fittings come at a pretty similar price point to some of EK or Alphacool's cheaper offerings.They're brass, which means they're safe to use in pretty much any loop that doesn't have aluminium in it. They fit the specified tubing nicely, tighten well, and look quite nice when they're in; they're inoffensive and plain, and don't draw too much attention, and generally look pretty nice in a mostly white build.I can't quite tell if they're powder coated or just painted, but I think it might be the latter; out the package the paint is already stripping off a little bit, as shown in the pictures. I'm not too sure if this is from production, the way they were packaged, or the method of painting, or any of the above.Again, these are fairly inexpensive, and are similar price to some other budget fittings, but with the finish I think I'd probably opt for something fro say EK if you can get them for a similar price. However, these are actually a pretty fine option, they don't look bad, and some of this aesthetic stuff doesn't matter too much and isn't really visible, but it does leave something to be desired.
