Patented Lightning Tire Air Chucks by JACO
Lightning L2-Series - 1/4" F-NPT (2 Pack)
With time, comes evolution - and with evolution comes the all-new Lightning Series air chuck line by JACO. This progress is driven by those who demand high-performance air tools built to last for all-day performance in the garage or shop. We have completely revolutionized the air chuck from the inside-out with industry-first features - utilizing patented technology & lightweight, yet durable, aluminum alloy making our Lightning Chucks the most rugged, reliable, & easy to use air chucks ever.
- Automatic clamping design offers 100% airtight seal to tire valve stem
- Quickly disconnect with no air loss using the quick-release button
- Built to last from lightweight, durable, & corrosion-resistant aluminum alloy
- Open flow design allows air to flow freely through air chuck (no check valve)
- IMPORTANT: this is an OPEN FLOW air chuck and must be used with an inline tire inflation gauge; can NOT be used directly on the end of air compressor line.
Important Notice About "Open Flow" Air Chucks
Open flow air chucks allow air to flow freely through the chuck, even when not engaged to the tire valve stem. If your air compressor has an air tank, open flow air chucks can NOT be connected directly to the end of the airline without first attaching to an inline tire inflator gauge. If you connect an open flow chuck directly to the end of airline without an inline tire inflator gauge, air will flow straight out and empty your compressor's air tank. This air chuck must first connect to a compatible tire inflation tool that supports 1/4" NPT threaded attachments, such as our FlowPro Tire Inflator Gauge series or similar tools that can open and close air flow from compressor.
The thread specification of this chuck is female 1/4 inch NPT.
Please make sure to confirm your application and fitment prior to purchase.

Lightning fast release from the tire valve stem with absolutely zero measurable air loss thanks to our proprietary quick-release button.
Superior Compatibility
CNC machined with precise 1/4 inch NPT female threaded fittings for endless compatibility with your tire inflation air tools.
Built To Last
Engineered from durable, yet lightweight, industrial grade aluminum alloy that won't rust, corrode, or weaken over time.

I bought this to use on my motorcycle which has limited space for hands and connectors. It worked better than I was expecting. Very easy to use, no leaks, easy to remove - exactly what I was looking for.I forgot that in my case I needed an adapter to convert the "hose" end to a 1/4" M-NPT, but I actually had one on hand. I would've liked to only buy one at half the price, but overall I'm satisfied.

High flow. Well made. Press on the stem. Rotates easily. Works great for tight lawnmower and golf cart time where it’s hard to access stem straight on.

I’ve tried so many air chucks in the past and they’ve all had their problems. Even the self latching types seem to have at least minor leakage. It’s something I’ve just come to terms with. This one does not leak at all, at least so far anyways. It seems to be very good quality, and super easy to use. The 90° angle also makes it easy to get into hard to reach areas. So happy with this purchase!!

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.

These things really lock on and hold without air leaks when put on square. Easy release without air loss when you are done setting your air pressure.Highly recomended for tight spaces, like behinde motorcycle front rotors!!

Been buying and trying tire chucks for years. Want something that’s easy to put on the valve, seals well, stays on, and doesn’t require a contortionist to make work. My search is over - these are great. Slip on easily, stay on until you push the button to remove, don’t leak. Score!!

I've tried a few air chucks and always had issues with leaking. I tried this today and it worked perfect. Locked into the valve stem, no leaking, and unlocked easily. My sanity is restored!

I use this to upgrade my Milwaukee air pump at work perfectly. You don’t lose any air when you disconnected. I highly recommend it.
