I just bought a 100-foot air line from Harbor Freight and snaked that through the walls from the garage to the basement shop. I added a moisture trap and a regulator at the basement end. The compressor runs at 125 psi and I can cut down the pressure in the shop to anything I need for pin nailers, etc. This is really convenient and probably cost less and took less effort than any kind of plumbing.
That being said, a friend used ordinary CPVC pipe which is rated at 200 psi.. |

Bad example. |

Just because those videos do a terrible job of explaining why you shouldn't use PVC with air doesn't mean that you should. For example, if that second video had given any indication of what PSI caused the failures they would be perfect. Since they don't, we have no idea if the test resembled real world conditions or were just done for effect. In other words, they weren't very "instructive" other than to proof that you can indeed cause PVC to shatter while under pressure. Freezing the pipe apparently helps too.. |

I'll make sure I label it as "instructive". https://www.youtube.com/watch?v=WeKA0eImhWQ I'm pretty sure that you, being the intelligent gent that you are, would be one of the first to point out that we know very little about the root cause of that explosion. Our *experience* tells us that the situation is out of the ordinary, therefore we wouldn't consider the video to be "instructive" as it relates to the "Never, ever, ever" warning given. Regarding the PVC video linked to above, we don't know if they tested that PVC with 60 PSI or 600 PSI. To be considered "instructive" (and that *word* is the only thing that I'm talking about) the video needs to tell us something about the test conditions. To be clear, I am *not* recommending or even suggesting that PVC be used for air under any conditions. My only point is whether or not those videos can be considered "instructive" in the context used. |

The compressor runs at 125 psi and I can cut down the pressure in the shop to anything I need for pin nailers, etc. This is really convenient and probably cost less and took less effort than any kind of plumbing. That being said, a friend used ordinary CPVC pipe which is rated at 200 psi. And he may luck out and move before it breaks, or he may luck out and there not be anybody near it when it breaks. You might find a couple of videos instructive: https://www.youtube.com/watch?v=IVO4_hUvFsc How instructive is a video that shows that they couldn't get the PVC to shatter until they battered it numerous times with a weight of an unspecified amount from a height of 12' and then *froze* the frigging thing? For all we know, it would have shattered at 0 PSI after taking all that abuse and then being frozen. Heck, for all we know, it would have shattered the *first time* at 0 PSI once it was frozen. Bad example. It may have shattered without pressure but it wouldn't have exploded, throwing shrapnel. No thanks. https://www.youtube.com/watch?v=w1x1UxbD7B0 How instructive is a video of some guy who says nothing more than "Don't do it" without anything to back up his words other than some videos of PVC bursting after being subjected to...oh, wait...we have absolutely no idea what it was subjected to. Bad example. No, not at all but you're welcome to experiment with your life. Nothing I said indicated that I plan to use PVC for high pressure air or that I suggest anybody should. That *was* the subject. There's a big difference between pointing out bad examples vs. disagreeing that with the main concept. Just because those videos do a terrible job of explaining why you shouldn't use PVC with air doesn't mean that you should. For example, if that second video had given any indication of what PSI caused the failures they would be perfect. Since they don't, we have no idea if the test resembled real world conditions or were just done for effect. In other words, they weren't very "instructive" other than to proof that you can indeed cause PVC to shatter while under pressure. Freezing the pipe apparently helps too. Except that I don't want to be anywhere around it when it does. That's good enough for me. You welcome to risk your life foolishly. What is it that prevents you from understanding what I am saying? Your illiteracy. Ah, you've been talking to the reflection in your monitor again. Now it makes sense. |
