Mini B

[scubadragon]

I have a 27 cu ft tank that has dot markings on it but was made in australia for an english company then sold by diver discount.com in the United States. The problem is that it has an english metric thread on the valve and as yet I have not found anyone who can hydro this tank. Can anybody help me with this?
Thanks

Can they not hydro it because of the thread (m25x2?) or because they dont know the specs?
Is this for a Mini B scuba system? We have been looking at one for our voluneer coast Guard crew. Any coments on it?

The DOT markings are a good thing as they make it possible to find ahydro tester in the US that will requalify the tank. If it is DOT marked it should either be a 3AL or 3AA standard tank or they will have the exemption information needed to properly test it. So the lack of specs issue should not be an issue.

That issue aside, the hydraulic fittings on the test equpiment used by a given hydro tester are probably standard, and should easily quick connect to the proper metric fitting for the tank - but you will probably end up having to buy the fitting yourself as no one is going to go to that expense for a tank thread they will rarely if ever see again. My suggestion is to get with the hydro tester to see what is needed to enable them to test it and then plan on paying for the adapter(s) yourself.

If it does not have DOT markings it cannot be legally hydro'd unless for immediate export from the U.S. A hydro facility that would hydro it is at risk to lose its DOT license.
