Here's a link to an ebay listing.....
http://www.ebay.com/itm/Carleton-4500psi-60min-SCBA-Carbon-Fiber-Cylinder-air-tank-Mfr-Date-2001-6109-/331911755844?hash=item4d477b7844:g:gbgAAOSwZVlXjGWM (http://www.ebay.com/itm/Carleton-4500psi-60min-SCBA-Carbon-Fiber-Cylinder-air-tank-Mfr-Date-2001-6109-/331911755844?hash=item4d477b7844:g:gbgAAOSwZVlXjGWM)
These have an unfamiliar type of valve, can anyone provide info?
Other than the fact that these tanks are at or have exceeded their
useful life, could there be anything else wrong with them?
The seller also has tanks with the standard looking valve.....

All thoughts/opinions appreciated.

Expired is EXPIRED ... can't get it hydro tested OR filled by any commercial source

I wouldn't waste time looking at those tanks. Like the man said, expired is expired, & they would be useless to you unless you plan to re-purpose them in a non pressure containing manner.
On the second unit that's months away from expiration, if the seller would be willing to drop the price a bit it you'd possibly get a functional tank valve at a decent at a good price. Provided the valve is functional & doesn't have any structural damage.

I thought I saw where they upped the 15 year lifespan to 30 ? I would have to dig to locate the information and admit I may be foggy on it.

The Navy requested a consideration for this but that don't have anything to do with the DOT 15 year life span requirement. They sell tanks that have a 30 year life but they are so expensive it wouldn't be worth it to airgunners.

Here is a thread about the "re-certification" of CF tanks. It's not a done deal, but supposedly will be happen soon. Key word is supposedly, but remember it involves the gov't.

Don't take a chance on buying expired tanks.
The extension, as mentioned, was for the Navy to do some testing of their cylinders. We just hoped that if one set of cylinders were approved the extension, that others would follow. and eventually all CF cylinders.
Don't hold your breath on this, buy a tank with the focus on the 15 year shelf life and pay accordingly.
-
Besides, the top link cylinder you would need to purchase a valve assembly. And that would cost more than the cylinder.

On a $/year of service, the 30 year tanks are about 2/3 the cost of a 15 yr tank. Just as with used 15 y-o tanks, the only sensible thing to do is buy on the cheapest $/year remaining...and for the folks who are not sensible, they will be happy to even further reduce your cost when there is about a year left...:D
