JACO Lightning S-Series Tire Air Chuck - 1/4" F-NPT (Open Flow) (2-Pack)

Very sturdy you can tell from the weight of each one that it’s not a cheap plastic thing I bought an adapter to attach this to my portable air compressor and it works perfectly no more screwing and unscrewing the hose fitting to the tire valveThey lock on the tire valve with a push of the button and the same thing to release and they don’t leak air while attached or when you’re moving it to the next tire I recommend this

I have this mated with a npt to inflator adapter on my Milwaukee M18 inflator and it works flawlessly. I made the mistake of buying those generic quick connect adapters which just leaked air all over. Stick with Jaco, worth the cost for superb quality.

I used the air chuck once on a track day to adjust the tire pressure. It was well made and easy to use by sliding the air chuck over the valve stem. It held onto the valve stem well without leaks. It was released by pressing on the side liver. It worked as instructed.

Works great easy to use.

I was skeptical at first. I put one on an older Amflo 112 inflator. Well, the threads are different. So I had to buy a new hose for my inflator. Bummer. But I was pleasantly surprised when this didn’t leak! Works as advertised.My only gripe and the reason I knocked it down a star, it’s a little large. Handles easily but when screwed onto a hose it becomes too cumbersome to be used with some wheel rim and valve stem designs. Works great on my car, but the turbine wheels on our 80s F100 pickup are too tight to use this. A smaller version or maybe I’ll make another with a 90 degree fitting on it, since I had to buy two. Less expensive than the Lock-n-flate I wanted to buy but sold out when I got these.Good value!

I love how easy it is to pop them on and off! It is 100x easier to use than all the other lever and screw types on my pumps.One negative was that sometimes the valve would be little leaky when attached and you would have to wiggle it to get a good seal. It doesn't stop it from working, though you just want it attached when actually working. So a little fiddly, but it is so easy to connect and disconnect -- totally worth it!I was able to mount one on a schrader valve (with a 1/4 NPT connection), and then I can insert it into my bike pumps, or DeWalt inflator, etc.

Used this to upgrade the inconvenient screw on style chuck that came on my Smittybilt offroad 12v compressor. Huge improvement! Had to also order a 1/4 npt barbed fitting for the hose, however that may not be necessary for everyone if you've already got a 1/4 fitting to attach to. This open flow chuck allows me to turn the compressor on and leave it running while I check air pressure with a guage since most 12v portable compressor don't have a pressure switch to shut them off when pressure builds. If the psi in the tire isn't quite there, just push the chuck back on the valve stem and keep filling. With this chuck you just push it on to the valve stem and it locks on automatically, no need to press the button and hope it locks on tight enough. The only time you need to touch the botton on the chuck is to release it. Its very easy to press on with zero air leak. Solid feel, and has some weight to it. They have a bigger model that might have been even nicer for a few bucks more.

It works great and doesn’t leak
