I've had the same sch 40 in my shop for 29 years now. only times it's broken was when I hooked a line with the hose or ran into it with something. but then I only keep my air set at 95-100 pounds. If I were doing it again I'd use galvanized or copper however, as the plastic maks a BIG bang when it breaks. an old fart like me could have a heart attack the next time
