I knew this thread would eventually get Thrashed about the use of PVC
and is very well justified
although there are some precautions can be made if choosing to use it...
You folks that plumb your shops with PVC or have future plans to do so, there is one step you can take to limit the risk of danger if the PVC were to give way and explode,((wear armer clothing, head gear and safety glasses))
just kidding
really though! you can feed the pvc through a larger conduit pipe, or better yet steel pipe, although by the time you have done this you might think about the cost and then go ahead and use primarily Glv steel pipe to Begin with, I know for some of us not having access to a threading device is what keeps us from using steel in the first place, how ever most home improvement supply stores can thread the pipe for you for a fee per each threaded end, if you cannot get the pipes threaded and decide to go with PVC? then as I said the next best precaution is to shield that PVC inside another pipe, even though the nipple for the QC would be still exposed outside the the shielding pipe you could heavily wrap this part in duct tap just in case it were to give way at this point the tape would help to hold back scattering particles, the schedule 80 cpvc is the best choice if having to use it, and is actually what I used in my shop, but I drilled holes in the wall studs and and fed the pipe through and finished the walls in 7/16 of OSB so the pipes are actually behind the sheathing, I regulate down to 100 psi fed to these lines, My compressor is capable of 150 psi, and sits in the inside front corner of my shop, I fed a Galv steel pipe through to the outside and then to a hose real that I can turn up the psi to 150, there is enough hose 50ft to feed back inside my shop if I need higher air supply, but usually for my nail guns ect, all I need is between 65-100 psi, I used the 150psi for things like loosening/tightening bolts or sand blasting, air sanding etc,
