"All of these pieces work as advertised."
"Solid brass is the only way to go for high use, but these are nice for air tools that aren't used too often."
"Everything I needed for my air hose and compressor accessories."
"What is more impressive is that they hook up to my old air guns that are over 30 years old with plugs that are as old as the guns and there is no hissing or leaking of air!"
"I'm using a Bosch industrial connector on the end of the hose that connects to the compressor and the red Color Connex type D on the end that connects to my tools."
"They would probably good for the hobby guy that doesnt use air that much, but if you swap out tools on your airline often expect them to wear fast and start leaking air."
"I installed these with my new hose and it leaks worse than my 5 year old one that was a cheapie from the local discount store."
