First of all you have to find a different 4500psi rated quick dissconnect fitting that has a 1/8" bspt/npt thread, then change every 4500/5000psi rated preset/air system. Great idea if you're the only company selling such a fitting, you'll make a fortune.surely changing nipples would be cheaper and a more effective solution than a blanket ban on 3000psi bottles. Considering 3000psi are more in use in this country...
