I ran pex through out my shop and even 3 runs from the barn back to the house for a fitting in a closet upstairs, down stairs, and in the garage. Been that way since 2004 with no issues at 150 psi.

I also plumbed my (125 PSI) shop air with schedule 40 PVC nearly 20 years ago. I too have a short length of rubber air hose between the compressor and the pipe. The number one issue with PVC is the derating when it gets too hot, and the section of hose does help limit that. Ignorance is, after all, bliss.
I suspect that by now, I would have had more problems with galvanized pipe rusting through.
Oddly enough, it's the PVC water line that burst one winter when we had sub-freezing weather for about two weeks (I live in Florida). I went out to my shop and heard a hissing sound as I approached the door. When I opened it, I was greeted by a beautiful winter wonderland display covering almost everything inside. The pipe had split just the right way to create a very fine fan of water aimed perfectly to cover at least 500 square feet or so. I had to drill a hole through the back wall (and sleeve it with copper pipe) to let the water drain out.
I fixed it and put one piece of pipe insulation on it, and have not had any freezing problems since.
And just this weekend my son returned from our "gazebo" on the lake with the water filter parts in his hand. The top looked like it exploded when it froze. I guess it got cold in the little bathroom a few weeks ago...
So far, freezing is worse to me than compressed air when using PVC.

The Harbor Freight kit would be very hard to beat, BUT, it is probably China built. If you put it where it can be accessed if problems happen, you would be better off.

It all depends on how lucky you are. Not every PVC airline installation fails. If they did, we probably would not be having this discussion. I just don't want to be around when the random catastrophic failure does happen. And it will not happen in my shop.
The jury has decided, and the case is closed. PVC for air has been proven to be unsafe. People have been injured, and it has been banned for such use, by everyone who regulates it.
Any anecdotal evidence to the contrary, does not prove otherwise.
Anyone who uses it, is playing Russian roulette. Which, by the same logic is also safe, if the gun does not go off.

They way I see it, if you feel comfortable with PVC go for it. I think we are all aware of the danger. Some of us dont wear seatbelts, smoke cigarettes, and eat cheeseburgers from McDondalds. It's all a matter of what you feel safe with.
