Reply To: MSA and scuba tanks
I’ve been SCUBA certified for over 35 years and I have yet to know of a life span for a steel or aluminum SCUBA tank as long as they can pass a hydrostatic test every five years. To my knowledge it is only the composite skinned tanks that have the 15 year life according to DOT requirements. It should be easy to tell if your MSA tanks are metal or composite on the outside but the real test is whether the hydro dates are stamped in the metal at the top (metal tank) or a sticker on the side (composite tank). If you are still unsure take them to a paintball refill station or SCUBA refill location because as has been said before those tanks have a lot of stored energy in them when full and are like a bomb or a rocket if they rupture !!
