It’s good.
I was a little skeptical after trying various other fittings. I use this with my Powertank CO2 system for tyre inflation. Get the OPEN version if using a trigger gauge. This locks on well once you give it a good push on and release the lever. No leaks and fast to attach/detach. I gave the moving parts a bit of motor oil just to smooth the action and reduce any potential wear

Chunky chuck
The chuck that came with my tire inflator gauge was just a cheap, standard chuck. It never really grabbed squarely onto my tire valve stems. I had to keep one hand on it pressing inward and I would still get air leaks. This chuck is a little pricy but much better quality. The teeth are chunky, the product itself is chunky. You can feel the stoutness right out of the package. It locks onto your valve stems securely so no need to keep a hand on it. I get more accurate PSI readings on my gauge and a quicker fill-up since there is no air loss. Screwed onto my existing male 1/4" NPT so nothing to complain about. I recommend.

Calidad inigualable.
Desde que lo sacas del empaque se nota que los materiales y la construcción son de primer nivel. Este adaptador/mandril/cople para inflar llantas es solo para los pocos que están dispuestos a gastar 50 USD por dicha herramienta. Pero no van a encontrar ningún otro que sirva tan bien como este o que esté tan bien construido, así de simple. Y ahí entenderás que vale cada centavo y que es un pequeño placer cada que lo usas.

Expensive, but a fantastic addition to any tyre inflator. Well worth it
Hard to come by, but a fantastic addition to a tyre inflator such as my Milwaukee. Really helps attaching quickly to the tyre valve. Just remember if buying outside the USA, the thread on the air supply side is NPT.

Extremely well made
This is the ultimate air chuck. After using their grease connector for several years when I saw they had an air fitting I knew I had to have it. Installation was easy and now I get a quick, reliable,leak free connection to fill tires. I used a small adapter connect the lock-n-flate to my Milwaukee M18 inflator.
