S2-Series

Great tire chuck, easy to use and no leaks when filling the tire. Locks on securely and easy push button release.

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.

My wife was having trouble connecting a regular air chuck with locking mechanism, so I decided to purchase this air chuck. She can now attach this air chuck like magic and remove it with just a whisper of air loss. Connecting to the valve stem is so simple, just shove it on and it auto locks to the stem with zero air loss. Removing the chuck is also simple, just push forward the release and it releases like magic. I have no idea who designed and engineered this air chuck, but it is genius. Buy it and you will be amazed how easy it is to attach and add air. I am not receiving any compensation for this review.

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

Easy to install and good quality.

I check air on my 3 cars every weekend, especially in the winter. Older cars - the bead doesn't seal as well as new. My old connection was fiddly and I had to take off gloves in (bitter cold) winter freezing my fingers. This is on/off easy. And it doesn't leak. A good buy.

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.

These are great. Saves a bunch of time to just snap on and measure. Got one on my inflator and another one on my gauge.

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

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.

Every now and then you find a product that just works. It does exactly what it says it will do. Yeah it's expensive but you get what you pay for. I bought these to build a better hose/chuck setup for my VIAIR 300P. Best air chuck I have ever used by miles and miles.

Good quality
