Took my tire pressure gauge to the next level after easily adding this chuck end to my ElitePro™ Digital Tire Pressure Gauge. Love how it connects and holds and easily disconnects when done. Little to no air escapes when using which is a huge plus vs other style chucks ! Yowzer

I originally tried your chuck with the 90 degree angle and fell in love with it so I had to purchase the S2 for different purposes

Great customer service! Responsive and understanding to ensure that product meets customer’s needs. Will certainly order their products in the future.

I own 7 tire JACO gauges, 1 in every vehicle and in my Garage. My aircompressor is connected to a 1FlowPro® 2. 0 Digital Tire Inflator with Pressure Gauge and the air chuck wouldnt attach securely to the valve stem anymore. JACO sent me their Lightning S2-series chuck and it is fantastic! it clamps securely to the valve stem, the first time, no leaks and allowed me to get an ACCURATE PRESSURE! WONDERFUL AIR CHUCK!

I ordered 2 air chucks on Dec 11th and 2 air chuck adapters I received the 2 air chucks on Dec 15th And still waiting for the 2 air chuck adapters. It is now Dec 23rd and no information on the status of the adapters. Question, why didn’t the adapters ship out the same time the air chucks got sent out?

The lighting s2 are the best air chucks available,I have seven vehicles that these chucks are used on and the oldest one is over twelve years old on a tire gauge from Jako. Their products just don’t wear out.

You can't beat this air chuck. Fast and tight with no leaks. I am buying another one for my bicycle air pump. I replaced the standard chuck on the Jaco digital air pressure gauge with the first Lightning S2 air chuck that I purchased. Great for accurately finishing airing down with one hand using the bleeder valve on the pressure gauge.

Great designed, the chuck grip onto the valve solidly.

Excellent air check, operates flawlessly with a good seal. All my products from JACO our top quality and very precise. With a lifetime warranty when you register. You just can't do better than that

Locks on super easy and pops off with the button even easier. Quality materials and should last a long time.

Thes are much better to have than a screw on tire inflator fitting as these are quick and easier to use.

There is always the best of the best no matter what you’re needing. These are just that as far as air chucks and adapters go.

Fits on my valves and holds and doesn't lose air when removing. Makes it easy to fill my tires

2025-02-15

High quality product that outperforms the competition

Works exactly how it should. I have had no issues what so ever with it unchucking. And seems to be a great machined part!

The JACO S2 air chuck and the Milwaukee M18 inflator fit together like peas and carrots -- after you add a 1/4" M-NPT \ M-Schrader adapter. The S2 doesn't leak at all. . . and releases instantly.

Works flawlessly with little or no loss of air. A real asset for arthritic fingers. The only downside, I had to buy a valve stem adaptor to connect to my tire inflator. Would be nice to have it connect to inflators that have valve stem fittings instead of 1/4" fittings.

I bought this and the adapter to hook up to my milwaukee tire inflator and I love how easy it is to hook up to the valvestem. The swivel head makes it even easier to hook up without have to twist the hose. Removal is as simple as pushing the button. Alot easier and faster than screwing it onto the vavlestem witch will be realy appreciated in the winter. And doesn't leak air when hooked up(I did put Teflon tape on threads just to help with no leaking) I would definitely buy again and highly recommend these.
