QWORK Mini Ball Valve, 10 Pack 1/4" NPT Thread Female and Male 304 Stainless Steel Shut-Off Valves

Valve seems to be good quality, smooth function. I am using this in front of an air pressure regulator on my compressor to keep the air from leaking out when not in use, no problem holding 150psi without leaking

Great

Looked nice but doesn’t shut off in cold temperatures. Ball valve was closed and it is leaking air at temperatures below 20F, which meant that the air compressor in the garage kicked on about every hour or so.. Not well made or made with wrong material inside where the ball seats..

No leaks, I use them everyday. I haven't had to tighten the knobs or anything. Will buy again!

perfect

I figured that 304 stainless steel would be suitable for drinking water. The problem is they are assembled with some kind of petroleum lubricant (you can smell it) I tried washing with dishsoap with no improvement. Then tried white vinigar with no results. Finally washed in the dishwasher. This removed the odor until you actually opened and closed the valve and the lubricant was again exposed and the smell was obvious. I would not take a chance and put drinking water through this valve. It looks like the construction is good and will use them for air or something else in the shop.

These valves are built like Fort Knox!

Me llegó en 6 días al Callao en Perú. Se aprecia de buena calidad las válvulas.
