Bitspower G1/4" to 1/2" ID, 3/4" OD Compression Fitting V3 for Soft Tubing, Matte Black, 4-Pack

A bit tough to tighten but overall great. Just don't do a bunch if you want to keep the feeling in your fingers...

Well built, sturdy and had no leaks!!!!

Exactly as advertised. After having to buy these individually in the past it is refreshing to be able to just get a pack of them.Product arrived on time, in good condition, and as specified.As a tip to new builders, these fittings are a pain to get on without cheating. Once you cut the tubing take a small nick out of the OD, such that the outside surface of the tube remains contiguous. This small nick allows the screw to start threading,and makes the fittings take about 1/4 as long to get water tight.

Great product. Bitspower is slightly on the $$ side but quality=$$. Got these over a month ago and no signs of leakage. Paired with primoflex tubing, a really tight fit and when you add the compression fitting its double protection. One minor gripe is no white ones.

Nice and tight fit. Very tight. The thickness and build quality of these fittings is great.I had no problem getting the tube over the barb. The Compression Nut was a bit tight but I managed to get it to work without having to clip or nip the outside of the tubing. This might prove to be a challenge if you're having to do this at an awkward angle. I knew this because I read a few reviews about these fittings before buying them. I really don't care either because the fruits of the labor is a decreased chance of leaks.I would speculate that the Matte Black finish wouldn't interfere with a Silver Kill-coil. In my first waterloop I used a Silver Kill-Coil with Nickel fittings and after a year I could see the Nickel wearing out. Silver reacts with Nickel, which causes the Nickel to flake off.

Good quality but hard to work with.
