JACO Lightning L2 Quick-Connect Tire Air Chuck - 1/4" F-NPT (Open Flow) (2-Pack)

Works great. Seals to the valve stem just like you’d want it to, without trying. It didn’t leak while using it with my Dewalt 20v air inflator. This won’t work directly with inflators. But find a1/4 NPT to schrader brass adapter. Solid combo to use with inflators.

durable, solid and easy to use. It connects securely to the valve and holds air with no leaks. A reliable little tool for tire maintenance.

I've been using another popular brand of quick connect air chuck for a couple of years. The other one works fine unless it's cold out (below freezing), then it won't completely seal to the valve stem. The other one was almost twice the price of this one. I should have bought this one to begin with. This one pushes onto the stem easily, seals completely in cold weather and releases quickly with almost zero air loss. I also appreciate the smaller form factor of this one. This one feels well made and swivels smoothly. I'm using this on a portable inflator I keep in the garage for when my compressor is overkill. Purchasing another of these to go on another inflator I keep in my vehicle. We'll see how it holds up but initial impressions are very good.

These function just fine except that they can be fiddly to attach to or remove from the valve. If you're angled just a hair, they'll jam going on or off. Not a huge deal, you just have to develop a bit of technique. But I knocked off a star because of that. Once attached they seal to the valve perfectly, and stay put with no leaks until you press the release. Just like they're supposed to. No complaints so far about the quality, they seem solidly built. These are the only air chucks that I've found that allow me to air up the spoked rear wheel of a Harley Highway King. Nothing else I've tried is able to get past the gauntlet of spokes, brake disc and drive pulley to reach the valve. Not even the official Harley inflator, which claims to enable access to "hard-to-reach motorcycle valve stems", will work on my bike. So I'm very grateful to JACO for these chucks. I'd be happier if they sold them in a pack of 1. Why was I forced to buy two of them? The extra one is sitting in a drawer where it will probably remain for years. Well at least I have a spare. Four stars for the product, one star for "value for the money". These are free flowing chucks - no internal valve. If you connect directly to an air hose, air will noisily rush out. Many reviewers have complained about that (can't they read?), consider your application before purchasing.

Works amazing! Just need an adaptor to fit shrader valve!

We have an RV and keeping the tires at proper inflation is a very important safety item. It was a morning chore that I dreaded until I got this thing. The RV has 6 big truck tires and they take a lot of air. With the old chuck I would struggle to hold it in place and not leak. With this one, I just stick it on the valve stem and it holds on until I am done. Press the button and it lets go -- very simple, very easy. Note -- it comes in 2 flavors, open flow and closed flow. I am using an inline pressure gauge and I want a reading when I stop adding air, hence the open flow. If you check pressure with a separate gauge, get the closed flow; otherwise, you would drain your air tank when you remove it. Wonderful device. I will try to do a quick video one day.

The best air chuck for tire inflator. Swivel feature is redundant if your hose already has a swivel feature. Go with S series Jaco chuck if you don’t need this added swivel feature.

These work great! Bought the 90 degree ones first but they are hard to use on car tires. Prefer the straight for all around use.

Does everything that it says on the tin and then some great buy.

Push onto tire valve stem, no leaks. Amazing in cold weather, when your hands are cold. So easy!! When your done filling tire, push the little side button, it unlocks I would HIGHLY recommend

لا تعمل بشكل المناسب.

Good stuff

I don't know why I hadn't "meet" this device any sooner. It is simple, efficient and works really well. Sounds obvious but once tightly screwed onto your inflator hose, you just have to put it on the valve and it "airtightens" automatically without you being obliged to maintain it strongly pressed towards the valve. Great piece of equipment, I can only recommend it.
