How about a little more info? Is it a steel or aluminum tank? Is the valve tapping NPT or does it utilize a non tapered thread and an O-ring?

You need a good quality air pressure regulator to reduce the scuba tank's potential 2000-3000 psi down to the ARB's 90-100 psi. Personally, I would not use a scuba tank for that purpose.

When you have a choice, buy American made.

You can have that SCUBA tank converted to nitrogen or CO2. Last one I had done cost me 35.00 if I remember correctly. That was a hydrostatic test and a new valve. However if you just watch CL you can sometimes pick up ready to go CO2 cylinders for that price or less.

i dont think he is going to be using the tank at the standard pressure. the way i read it is he is getting a compressor for the ARB so he could use the scuba tank as a tank for the compressor.

your right im using a high volume arb compressor im thinking about using it as just a tank. would it be better just to buy a real tank or use the scuba tank. i figured if i decide to mount it under the jeep the scuba tank will hold up better outside. Im not sure if i will use it on the outside of the keep just keeping my options open.

The problem with using that tank for a compressor is that you only have one port. What are you going to do for a water drain?
I suppose you could drill and tap whatever other ports you might want. Although a regular 2gl. tank is fairly cheap and has mounting brackets and plenty of ports.

I seem to recall if you take the valve out of the tank it is a standard 7/8 NPT. Maybe you could drill a hole in the side and have a bung welded/heliarced on so you can have an inlet and an outlet. Dunno if this is what you are after.

Those who say it cannot be done should be quiet and not interrupt those whom are doing it.

Oh ok yeah as TiredOldMan said, a scuba tank is not suitable due to its single port, plus they are HEAVY. Just get a standard 2.5 gallon air tank, they have all the necessary bungs (ports) to make the whole job a lot easier.

When you have a choice, buy American made.
