Picked two dive tanks at the local garage sale, any good to somebody as an air tank for your rover. Last tested 1977 on one other n/k.

No good to me (I got compressor)

Would assome the valve would have to be removed for shipping?

Lots of those old aluminum scuba tanks are not easy to get re-certified. And I don't think you can fill them with CO2 because I think the CO2 valve doesn't fit the top. But I could be wrong about that.

There maybe a way to make it work I don't know about but I looked into converting a still certified tank over to use a powertank 2nd stage regulator and you would have to re-tap the tank to screw in a CO2 first stage regulator. That didn't seem very cost effective to me and either way you still had to spend a boat load on the powertank 2nd stage.

The one with the blue old school BC would be cool just to hang on the wall.

they where free to any takers (bar shipping), but I will turn them into yard art now, will make good wood chimes.

Or maybe weigh them in with all the freestyle wheels I got.

My comment wasn't meant to cast a shadow on your offering, just a commentary on how I had the same thought but nothing is ever as easy as it should be!

If you want, I just a plasma cutter and could cut a shark bite outline in the tank!

Plenty of cheap CO2 bottles on Craigslist from guys who got board brewing their own beer. GLWTS sale of the scuba tanks.
Sorry to get off the topic of really cool free vintage scuba tanks but do you know if the flow rate on a regular CO2 first stage regulator is the same as one of the power tanks? The guy I asked at the company didn't really answer my question and just went through the obligatory speech about how their tanks were better and safer than a steel tank.

The regulator is what dictates the flow not the tank. I'm sure the PT version is better but for 99% of the PT users they are filling up tires and not running high CFM air tools.

There is no first and second stage regulator. There is a valve, and then a regulator that is attached to the valve.

when you get your tank filled, you take off the regulator and the tank gets filled through the valve.

The valves offered by powertank are just regular Co2 valves near as I can tell. A good all-brass valve will cost you about 40 bucks most places which is about what PT charges.

The regulators offered by PT are touted as having a higher flow rate and pressure range than the typical regulators used for beverage service or other common applications, and claim to be more resistant to freezing up.

its really nice to have the high flow rate and pressure of the PT regulator. Fills tires fast, and makes more pressure than any 12v compressor.

Not sure why the PT people say an alu tank is safer than steel? Lighter, for sure! I like my Luxfer tanks. Just upgraded one of them to a 15lb.

Sorry it has been a long time since I took my scuba certification and I got my parts mixed up.

So the valve on a PT is the same as the valve on a regular CO2 tank? Meaning, if you put a PT regulator on a non-PT tank it would have the same flow rate as with a PT tank?
