Astro Tools 3SB40 World's 1st High Flow 3-Way Air Swivel

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.

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

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

Works well, 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

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.

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.

I bought 5 of them and they work as expected

Excellent quality. Larger then others ive seen this size.

Had these on my air tools for years, I find them particularly useful with 3/8 impact guns, any air grinding/cutting tools, and my air hammer. They really allow me to get into tight spots and hold the tools at different angles that I wouldn't previously be able to achieve. It's also saved me repairing my airline hoses as I no longer have a stress point where the hose goes into the gun. An absolute fantastic buy, I don't think I could use my air tools without them anymore.

Bought this as a birthday gift for a co-worker and it got used for 40 hours a week for probably 10 months getting slammed into the ground and run over by cars. It still doesn't leak at all and has held up flawlessly to tons of abuse. Astro is my go-to tool brand when I need something reliable and with amazing performance (however my 1895 impact gun decided to make the anvil explode and I'm very very impressed by that)

Must buy for any working professional who uses air tools

Nice addition to their Onyx impact gun. Haven’t tested whether or not this swivel really bogged down any performance since I’ve only ran the gun with this on but it is likely negligible if any difference at all in my use case.
