S-Series

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

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.

Great product, no leaks

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

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.

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.

No corrosion at all. Still working great

Super quality 👌
