Repurposing 55" tall gas cyclinder?
Last pressure test was 2009 - due for a pressure test. That is not the issue. The tank had helium and is still equipped to fill helium balloons - if it had pressure. Costs at least 125 for pressure test and helium.
i bought it thinking it would be good for surface scuba diving from a boat. Turns out that is not as easy as hoped. Each gas requires a different valve for one thing. may not be possible to get a 3000 psi scuba tank hydro test done - don't know.
