TAILONZ PNEUMATIC Brass Hose Barb Fitting -1/2 Inch Barb to 1/2 Inch Male NPT Adapter（Pack of 5)

Good brass hose barn that work like I want them.

good parts

Very nice quality

As Avery C. and Marc Cram noted, these fittings are exactly the size of the ID of the intended hose as opposed to being 1/32 oversized as many other of this type of fitting are. This makes it imperative to use a strong clamp to keep them tight in the hose. I generally prefer using a ferrule rather than a hose clamp to hold these, since ferrules are more streamlined and less prone to failure. Whenever the hose diameter permits, I now use Pex expander rings rather than brass ferrules (which are more size adaptable). They are quicker, smoother and more easily removed if needed. I use the Pex rings for both air and water hose and they work GREAT!

5, but ID is a bit small, so as to restrict flow a bit, so I give it 4
