-Yes, it is in fact "right out".
PVC has a poor "fatigue strength", and after a certain number of cycles near its pressure rating, will at some point crack and fail.
It's not really an "if", it's a "when". It will
And when it does, it throws out shrapnel- it doesn't "peel open" like a beer can, it shatters like glass, throwing sharp fragments.
If it were as easy as using PVC, I'd have had a nice air line up over a decade ago.
But I want something that I can put up and have a high degree of trust in for years to come. The RapidAir/MaxLine stuff is relatively new enough it doesn't have a particularly long track record, but the technology behind it (the way the fittings work and such) is pretty mature. I should be able to be pretty confident that this MaxLine stuff will last me at least the next ten years, maybe twenty.
