Chunky but smooth
Have 2 of them. Work great after a few months. No leaks. Still swivel smooth. They’re a little thick but it’s high flow. It’s materials science. They’re engineers not magicians. Good tool. Buy it if you use high flows.

Minimal restriction, moves freely
No leaks, moves freely and minimal restriction. I use this swivel on a Matco 1/2” rex impact, which is very air hungry and my ear cant really tell a difference between a regular chuck and the swivel. Doesnt leak as long as you use air tool lube. Anodized color seems to stay on well

No hype, just facts
It has larger air passages than anything else that I've ever bought, and I bought one that said it was high flow but the passages were smaller than most standard swivels. It's also very well made. I have 5, 2 that get used almost every day and no leaks

Only giving 4 stars as I have not installed it as of yet on the new rivet gun also purchased but looks nice and well built

Astro Delivers Again
I bought two new 1/2 drive impacts and added the Astro high flow swivels to both. Very pleased with the quality and construction. I'll do a follow up after I've lived with them for a while.

You'll buy one, and then you'll buy more
I bought one of these to put on the end of a Tornado blow gun, thinking it might be marginally better. It's not marginally better. Its far better. Airflow is higher, the swivel movement is so smooth you don't really have to think about where the hose is, and its barely more expensive than the no-name ones you'll find at the big box store. I've got them on virtually all of my tools now.
