Great value
Good value for the money. O ring is a bit small so make sure to tighten well.

You get what you pay for
Are they cheap? Yes. Do they work? Sorta. A couple of the included O-rings were bad, and resulted in leaks during testing. I would spend more money on fittings next time. Not a good thing to cheap out on.

If your looking for aluminum fittings these aren't it, they are brass!
They aren't aluminum. After magnet and scratch testing I found they are brass with some sort of semi ferrous metal as well. I ordered these for an all aluminum cooling system and if I would have used them, they would have caused serious galvanic corrosion and ruined my system.

NOT ALUMINUM...
NOT ALUMINUM.... not sure what its made of but its not aluminum, I purchased these specifically because they state aluminum and in a water cooling loop, it matters.

Good quality. good paint coating
Very good, looks like quality. I recommend going smallest for anyone choosing lines for this would be ID 5/16 - for those with strong fingers you will cramp up getting 5/16 lines on this - for this who live in usa, but then you can use zip ties for clamps for testing purposes. It holds water on my 480 radiator - no leaks.
