And China loves you for buying all those battery powered devices. They are the source for 90% of the lithium batteries.
If you want to keep the pneumatic air tools, I might suggest a shut off valve at the hose fitting may work out OK. When the air is shut off and the pressure is bled off, the pneumatic connectors work really easy. A 90 degree shutoff valve is pretty simple, turn the handle 90 degrees and the air is either on or its off. If he shuts the valve off before he disconnects the old tool, he can blead off the air by pulling the trigger. If he has the valve shut off before he turns n the compressor, there won't be any pressure until he opens the valve. It could get cumbersome, but the 90 degree valve could be put on the end of the air hose instead of before it.
I was actually going to suggest this until I remembered a very long time ago, a friends grandfather came out into the garage to show us young guys how it was done. I hated seeing all the near falls from him tripping over the air line or getting slapped in the face by the one hanging.
As far as China "loving us", dude, if you think that the majority of what you touch everyday isn't from/farmed/sourced/assembled/blessed in China, your dillusional. Thats just like the people that buy electric cars and think they are doing their part, then turn around and EVERYTHING else they touch has been touched by petroleum products.
O.P. , best of luck
