Compressor fitting for outdoor use?

[Digital4n6]

I would like to install an outdoor air compressor fitting.

Running the RapidAir piping through an unfinished basement rafters to a Milton Filter Regulator Lubricator (1/2in. Inlet) on the interior side of a concrete wall then plan to plumb 1/2" cast iron pipe through the masonry to an external fitting.

Should any standard 45-degree fitting be good, then place it under some sort of weatherproof electrical box outlet cover housing? Here is a picture of what I was considering.

Will run an identical box for a 20amp outlet (not double gang, separate boxes for safety) and have it near my generator outlet box as well.

bump?

I use a standard brass quick connect in my Jeep CJ. Not the same as being outside 24x7, but is frequently exposed to the elements. I keep a black chair leg end over it to protect it. The chair leg end is a perfect press fit. Easy enough on and off.

when I was a kid, we had an outdoor fitting for airing tires in the driveway; it was just a standard brass quick-connect. It was horizontal, no cover, nothing plugged into it 99.9% of the time; it was there for many years and we never had any problems with it. This was in NY with snow, rain, etc.

I've had a few brass quick connects exposed to the elements. The parts with issues are the spring under the collar, and the steel ball bearings.

If you take it apart before installing it and lube the spring and balls liberally with a marine grease, it should serve for many years. Just angle it down so it doesn't catch rain.

Anyway, if you put a ball valve behind it, it should only take seconds to unscrew a QD and pop a new one on, so don't worry too much about this.
