    Used as adapter for Dewalt and AstroAl chuck- perfect
    Used this Milton 1/4” NPT tank valve and an Astro Al closed air chuck on a Dewalt DCC020I 20v air compressor (with LA-CO yellow has lime tape) and love it. The screw on/off connector of the Dewalt is awesome and will last longer. But for the airbags on the back of my truck screwing it off would drop the PSI a few and I was getting tired of that. I used this adapter to fit the AstroAl chuck to those Dewalt threads I’m happy with that. With the chuck not on a valve stem, if I turn the compressor on it’ll build to the set PSI fast and stop. Holds are tight, no leaks with the gas line tape used and this adapter. So after filling my tires and airbags I clip it right off. Perfect. Only down side is I then press the chuck stem against the screw of my rock tamer mud flaps to release the air from the Dewalt air compressor Line (otherwise the line still has pressure and is stiff), and this adapter has such good tolerances no air leaks). But it keeps everything right at the level I set it to be. All parts are perfect fits and hold great. A buddy and I put Firestone ride right airbags on his truck a few days ago, and he loved my Dewalt air compressor (he has tons of dewalt 20v stuff already and got me turned to Dewalt). So when he gets his I’ll be giving him the second air chuck and the second Milton 1/4” NPT tank valve.

    Just What I needed
    I’ve seen a water heater flush tool in this configuration made out of plastic. Decided to make a more durable one. I didn’t save any money, but I now have a tool for life.This valve worked great.

    one way gas/air valve
    These look well made, the real thing. The one that I installed on the top of my pressure tank generally works quite well, though it once didn’t seal. I only had to put a little more air in to get it to seat. It is a ball type seal, like a quality BB that plugs the opening to stop the leak. I may be sensitive to dust or dirt unlike a rubber seal.

    Works with jaco tips
    I use this with a jaco quick release tire chuck to outfit my DeWalt inflator. Otherwise I have to slowly screw the DeWalt to the tire and slowly unscrew it. Losing a little air, which for tires isn’t as important but with airbags it’s more noticable

    A+++
    Perfect for air chuck

    Exactly what it is supposed to be and do!
    This works exactly as advertised! It holds pressure perfectly and was easy to install. It seems to be made well and should last. I was pleasantly surprised to see that two came in this package! I must not have read the description well, because I was only expecting 1.Just FYI, I attached this to a pressure tank for resin and paint. This was a cheaper alternative to buying a compressor and works really really well! The picture attached to my review isy set up. I pumped it up to 30 psi a few hours ago and it hasn’t had an issue.

    An Absolute Necessity
    Air Tanks and Tires always seem to use different connections 🙄 Gee, I wonder why that is? Get these and you don’t have to worry about it. Well made, fit perfectly, superb quality. A bit of tape, and no Leaks whatsoever.

    Very disappointed as the site clearly led me to believe I was purchasing a box of 10. When it arrived it was quantity 1. There was even a picture of the box of 10 in the ad. Misleading! As far as the valve it was fine
