14 Inch Heavy Duty Brass Mini Ball Valve Shut Off Switch, 14 Inch Male x Female NPT Thread Pipe Fitting Water Air Compressor Shut Off Valve , Rated to 600WOG

This is the fourth 1/4" male/female ball shut0ff valve I've ordered. Each time I was sent a 3/8" male female valve, see pictures compared to the 1/4" male/male valve I also ordered which is the correct size. Note! Both valves are marked 1/4" & you can clearly see the valve on the right is bigger ie: 3/8" vs 1/4" the valve I wanted.

I use this on my Tire Inflation Kit for my Semi, it controls the Incoming Air Supply side from the onboard compressor via glad hand adapter to switching it closed showing the backside tire pressure.The inflation tool here is what I call the holy grail of dually tire filling tools because it checks the tires and the gauge face can be swiveled to face you in any direction, there is a blowoff vent valve to the bottom, T-handle on the front side for push or pull depending on the tire position - inboard or outboard, and the gauge is stainless oil filled and plastic abs lens for longevity.And I searched for valves that would be compact and work well on the front side to control this and this one fit the bill. No complaints.
