S-Series

Exactly what I wanted. Works a lot easier than the screw on inflation connectors. I was having a lot of trouble topping off my tires on my teslas. The fine threads were difficult to get started without losing pressure...both on and off. These quick connects solved that issue.

Nice connection without any air leaking..

Very good item, beond my expectations.

These are great chucks. Clip on easy and stay on until the release button is pressed. Remember that these are for air gauges only and are not meant for air compressors. There is no check valve to stop flow. For air compressors the S2 series would be used.

You push it on, it stays and seldom leaks. It not perfect but works 9 times out of 10. And you can remove and push it back on to solve the issue. It removes easily with minimal air loss. I use it with an inflator which automatically measures the air pressure and inflates the correct amount. I've tried multiple other connectors and you have to hold them to prevent leakage - which defeats the purpose. I knocked off a star because you have to reset them occasionally.

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 valveThey 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

I used this on a tire gauge and it works

UPDATED REVIEW 1/26/2024: Seller reached out after seeing my initial review and offered a full refund for the leaking air chucks. As promised, I raised the rating to 5-stars. Now that's customer service! I'll plan to buy from them in the near future.ORIGINAL REVIEW 1/18/2024: I own another JACO product prior to this (the extension version, which I love) and it doesn't leak when topping off air or just connecting it. For some reason, no matter how much I seated the connector to my tires, it seem to leak as if it didn't fully grasp the Shrader valve on my car. Obviously, I had only so much thread on the Shrader valve to get a tight seal. There was only one time out of the 10 that it seem to not leak air on one of the two S-2 Tire Chuck. Of course, I had used thread sealant tape on both end connected to a 1/4" F-NPT Milton male valve adapter.I removed the sealant tape after some trial and error and it doesn't fix the issue. When I reconnected the extension, it didn't hiss at all. Looking at the center of each JACO product, I noticed there was a slight difference in how it engages the valve core. As if its more suitable for longer valve stem on a dually than a passenger car.For reference, I prefer open flow rather than close flow as my compressor regulates and shuts off automatically after reaching the set PSI. The Shrader end on the extension lacks the "pin" in the center. I'll just keep them when I get a better compressor in due time.
