L2-Series

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.

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.

Finally an air chuck that just plain works. Just push it on and it seals on to the valve stem and holds the chuck in position until ready to remove. Just push the release button and the chuck pulls right off. Use closed flow on airline to stop airflow when not connected to valve stem.

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.

I thought I would try the less expensive JACO Lightening 52, before I dropped major dollars on a LockNFlate style air chuck. I am so glad that I did. One could not ask for a better air chuck. This JACO Lightning S2-Series Tire Air Chuck was the perfect addition to my RapidAir tire inflator. I had purchased a RapidAir K3015 Automatic Shutoff Digital, Preset Tire Inflator. The K3015, is a fabulous tool, but it is expensive. Even at a high price point, it comes standard with the old style clip on brass air chuck. The kind of air chuck that you have to mess with all the time to keep it from leaking air around the valve stem. I replaced the Included OEM chuck with a JACO Lightning. It was a 100% improvement. There is no fiddling or fussing with the Jayco. Just push it on the valve stem and you are ready for hands-free inflation. When you are ready to remove it from the valve stem, simply press the release on the side and it pops right off. Don't hesitate to order it. It definitely works as advertised. Note: Air chucks come in 2 types, open or closed. Only the “OPEN” style chuck will work correctly on any inflation tool that has a pressure gauge or a digital pressure readout, included on the device. A “closed” and/or self-sealing, shut off, type chuck, will prevent any inline tire pressure pressure gauge from working. That is because A “closed” self-sealing, chuck, will not allow the air flow back from the tire, in the opposite direction to put pressure against the gauge. Only use a closed chuck on an air hose that you do not want to deliver air, unless it is connected on a valve stem.

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

Wow, the best I’ve used on my motorcycle. My bike doesn’t have a lot of room to work with around the valve stem. This goes on so easily with zero effort and seals to the valve stem with zero air loss. It disconnects just as quick and effortlessly. A little hard to believe it works so well.

I am an old guy and stooping down and or kneeling is not fun for me. I had the kind where you hold down a lever, push it on, and then let go of the lever expecting it to hold it on the valve stem. If you are reading this, you probably know how well that works. A while ago I stumbled on one where you screw it on the valve stem. I eagerly bought it. At first it seemed great. It doesn't leak or come off. The problem is that the threads have to be aligned perfectly or it won't screw on. It took more bending and kneeling than my original one to get it on. Maybe a different brand would be better, I don't know, but there don't seem to be that many of that kind available. I really didn't want to spend this much, and I really don't need two, but I am glad I did. It really works amazingly well. Just push it on and it locks automatically. When you are done, push the little button and it comes off. It really is that easy. It seems to be made well and I don't expect it to wear out quickly. Buy it. You won't be sorry.
