Ok, so what I got are called flare fittings, and I suppose I ought to be using hose adapters or pipe fittings. So, would I be correct in thinking that flare fittings are a different size?
Question about fittings
I'm trying to put together a new spray rig and was going for a quick connect system, so I picked up some 3/8" air hose quick connectors and the necessary water fittings to make it all go together. The spray handle is 1/2". So I figured put a 1/2 to 3/8 adapter in there and I'm good to go. I went to Home Depot and got a Watts LFA-274 1/2" FL x 3/8" FIP coupling. It is just barely undersized by about .12". I got two of those and one that is double male and they are all the same.
Did I get a wrong style or something?

You may have some metric going on? how about some pics?
Yeah, I realize how hard it is to see what I'm talking about.
Here's a spray handle. I have 3 different kinds that I am trying to rig up, but they all have 1/2" holes.

In the bottom of it is a standard 1/2" hole. Into that I tried to put this 1/2 by 3/8 flare fitting.

It didn't fit. It was too small. They're both 1/2", I don't understand why they don't fit together. The flare fitting is also the wrong size on the 3/8 side where I tried to put this in. It's a 3/8 x 3/8 air hose connector.

It's because the chucks you got at hd are not 1/2" they are 1/4" Id. They are close to 1/2" od but aren't.
You should be able to get the plug (that is what the male hose fitting is called) with ½" NPT thread. If the bottom of the gun is ½" (which I don't think it is from the size of the handle) it should thread right in.
My guess is the bottom of the gun is ⅜"" NPT, the plug you show appears to be ⅜" NPT. Because it is NPT thread the measurements will not match at the tip of the plug and the opening on the gun. Teflon tape on the plug, screw it in and see if it snugs up. You should see about ⅓ of the thread exposed out of the gun when it is made up properly.
Air hose fittings do not work well on liquids. You should go to a hose fabricator in you area for these parts. Look up "hydraulic hose repair".

Check out www.dwdiesel.com. or give them a call. The hose guys name is Larry, he'll hook you up
More than likely the gun is either a 1/4" or 3/8" NPT. If there's a Grainger, Fastenal or even a NAPA auto near you take it there and explain what you want to do, they should be able to hook you up.
Well, I finally got it all figured out. Boy, was that frustrating! I hate trying to get fittings to fit. The flares are a different size. The handle is 1/2, but the air hose parts(THAT WERE STAMPED 3/8!) Were 1/4. Go figure!
Whew! Glad I got that done.
