When do i need to get a nitro tank rehydrated (i am new to this) i was just wondering how many years it is from date on tank thx for your help in advance.
every 3 years if its fiber wrap 5 if it's steel . there are also newer fiberwrap bottles that just came out that don't have to be tested for 5 years. they have a differnt serial number or something. hydrotesting costs around 25$ give or take.
