Trying to understand air couplers

[VolvoRyan]

Sorry to be late to the party on this but I decided it was a good opportunity to test/confirm the function of industrial plugs, V-style plugs, and Stedlin plugs with a Milton universal coupler. While I was at it, I did some flow tests on the various plugs all using the same coupler. For good measure, I threw in a couple tests using a 25' 1/2" diameter hose and a 25' 3/8" diameter hose.

Some of you might find it interesting.

That is *really* interesting. Thanks for doing that. Good gawd am I shooting myself in the foot with 3/8" hose.

I've had a 50' 1/2" hose on my comp for the last 15 years. M fittings were not large enough to get full jam with my IR-232 gun. I ran 3/8" T fittings for many years to get the flow I needed.

More recently, I tapped the comp with a fullsize 1/2" pipe output with G fitting, and now use V style at the tool end.

Not shooting yourself in the foot it if gets the job done. My main hose is a 50' 3/8" hose on a reel. It's super convenient compared to a 1/2" hose. It's really only an issue if you need every single bit of flow and you can keep a short 1/2" hose around for those occasions.

Excellent points. I think I have 75ft of 3/8". The tools (impacts, air hammers, cutoff wheels) seem to run fine at static 90psi.

Thanks!
