worked very well

Not perfect
They're decent quality but not perfect. They work fine for my application but they are not air tight. I'm using them in a low pressure welding gas application. I think they would be okay with liquid but I did not test this.

Good quality
Nice little valves for the cost. Thread size was right on. No leaks.

Poor machining. Avoid purchasing these.
The threads were incorrectly machined. The thread pitch is very obviously off, causing a significant leak. Buy something else.

work as they should
They are 1/4" brass ball valves. I used them in an air system and appeared to hold pressure. what else is there to say
R**T
They work but leak a bit.
They all leak around the ball just a bit. The threads are solid, I've tested all three for leaks with 90psi air pressure and they all leak around the ball. Dissapointing.

Can't beat the price
Good product, seems well built, small compact and easy to operate. I installed 2 on my compressor-1 for water drain the second for shutting off the air supply-so far neither one is leaking.

wrong size for me.
excellent price and quality. I needed i/4" inlet and outlet. The inlet on these is bigger than 1/4,

Good product for the price.
Very happy with the quality of the valves. I have used them for isolation on my air system as well as shut off valves for my diesel fuel tank going to my diesel heaters with no issues
