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

Works exactly as described...easily pushes onto valve and easy removal with 0.00-0.10 air loss. No fidgeting to maintain air input. Attaches to valve stem without having to hold it in place.

Bought this to use with my new car tire pressure inflator / gauge. Works perfectly. Never leaks. There is an open flow version and a closed flow version. Just make sure you select the correct one for your application

Great product, no leaks

The perfect match for my tire inflator, just insert it on the tire valve and is intant seal, to release just squeeze the release button, I'm very satisfied with product, highly recommended.

I thought it work very well and easy to use price a little high

Meh, so so. 2.5 Stars --Sometimes they work, and sometimes they don't. It is very valve specific. Sometimes I have to hold them in place, of which defeats the purpose. But other times they clip on and work great. It just depends on the stem. Update 11/22/2025 JACO reached out and offered a refund. Sounds like a company that actually cares. I declined a refund as I do still use the product, but would accept a new part. Either way, I accept the fact that the return window has closed and JACO has zero obligation to me for a refund at this point as far as I am concerned. I did not realize they have a lifetime warranty...Nice.. upgrading my review to 4 stars...Nice to have companies that stand by their products!

I love this thing. I don't care for the screw on inflators as they are sort of a pain particularly if it's cold outside. They also lose air as you're unscrewing them. The other style with the lever or whatever are even worse for me. I've read reviews that they lose less air but I have the opposite experience. Often I've had to struggle to pull them off all while air is escaping. I read about this product and was skeptical. But I suffer from sporadic optimism so I ordered this as well as the connector (Milton S-684-4 1/4" MNPT Male Tank Valve) so I'm able to attach it to my screw on style tire inflator (ETENWOLF Vortex S7 Tire Inflator). My first attempt did not go well. I screwed the connector into the chuck but only hand tightened them. Leaked air like crazy. Then I properly connected them using actual tools and even added some plumbers tape for good measure. Perfectly air tight. You just push it on and to remove you just depress the button. A tiny bit of air escapes when you depress the button but it's negligible. If you've ever been frustrated with the standard types this is for you. Also since it just attaches straight into the tire stem with no lever or anything hanging off of it you don't have to try different positions to find the best position. I love this thing, for me it's a game changer.

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 valve They 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

Super quality 👌

Fantastic product, highly recommend it.
