: I'm a little confused? Why on a 3000 psi tank would someone put a 5000 psi burst disc? This is the test pressure that the tank is tested to. Most burst discs are usually 600 psi over service pressure and in this case it would be 3600 psi. You can't legally fill 10% over for safety reasons and that would only be 3300 psi. This is a serious safety concern.
: Hydro2go

Actually,These tanks are tested to 2 1/2 times their rated pressure,in this case 7500 psi for a 3000psi tank. If you have an overpressure problem(Probably while filling the tank) and your low pressure burst disc fails to work(Or you don't have one) you have a Burst Disc(In this case 5000psi)which can help exhaust the pressure in your tank before it blows up in your face(Not a pretty sight).Centerflag uses a 7500psi burst disc on their 420 series 4500psi tanks and it is the only one on the tank. Hope this helps
