Cheap and functional
Purchased to replace damaged drain valve on a compressor. They fit fine on 1/4" npt threaded pipe Price was good, and i have spares now.

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

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

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.

Worked for my installation
I wouldn't say they are heavy duty, but I like that they worked for me as expected.

Possibility of leak
Good valve, pack of three but two valves leaked so used all 3 valves to get a leak free connection but for the price good quality.

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.

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
