LP Tank Question

[Teller]

If a LP tank has the + stamped on it next to the born on date does the + have to be restamped after each hydro or is the original + good for the life of the tank?

Restamped each hydro.

 

[Teller]

And without the + the tank is rated for 2400psi. Does that mean a LP95 needs only 2400 to have 95 cubic feet of air or do you need to have the + 10% to get the 95 cubic feet?

at 2640psi -> 95cuft
