These are basic brass air fittings. They come with extra compression fittings, as shown in the picture, which is very nice.They are of good quality like you'd expect with brass DOT fittings, though no extras. Just plain metal.No issues with them.

Lost a star due to a couple of small things but should be included in the design. While it claims to be 350 psi rated, and the truck air systems today are will under that, I would have like to see a BARBED hose insert for that little extra. Also the spring could use an extra inch of length. It IS possible to kink a 3/8th hose diameter with the supplied spring guard.I do not dislike it enough to say that you should stay away from it, just it could be better.
