Abrasive blasting question

[jproaster]

One of my piped air lines is intended for abrasive blasting. I'm running 3/4 copper and I'm wondering if a Milton V coupler is a good choice if my intended purpose is to switch between an indoor cabinet and a 25' 3/8 hose out the window to blast outside.

I don't know how the cabinets hook into the air.
I'll have a regulator and water filter just before end of run.

Thanks
John

Milton v or a standard hi flow fitting would be great for a sandblaster line.
