Well, actually the question concerns a lot of the newer cheap guns that are designed this way. So in the pic, notice that there is a gasket and a spacer behind the brass air distributor. Now I haven't removed the air distributor on this Purple gun but I have on a couple other cheap guns I had, one was from my autobody supply store and the other was a Lowes gun, there are many others and some of them can be over $100 and still designed this way.
So my point is that on the two I took apart for cleaning, that air distributor was installed permanently with threadlocker. I finally got them apart but they both had so much thread locker on them that it was impossible to clean the glue out of the threads enough to put it back together and not get bits in the paint. It looks like for all practical purposes that you're not intended to take them apart, but fluid does flow behind there at a point and would need to be cleaned other than just blowing thinner through it. The supply house gun I gave away brand new with one use because I wasn't going to spend the time to clean those threads, that stuff was really hard to get out. The Lowes gun I took back, it was like $50 maybe more.
I see the Purple gun looks about like the same build and I haven't used it yet but at 10 bucks I don't mind throwing it away if I have to. But see many others made the same way and wonder if they all have that part glued in place and how are people cleaning them?
