Closed HP13 cylinder, Worthington X4-13, 3AA3130

[2airishuman]

For a very brief time Worthington made a series of small X4 and X5 high-pressure cylinders. These were 3AA cylinders and therefore have a thicker wall than most HP cylinders and have negative buoyancy. Like other galvanized HP cylinders of that era there is a round-out process that must be followed immediately prior to hydro or the hydro test will produce false failures.

Very few of the 13cf cylinders were made.

6.9 lbs empty
4.24" diameter
12.5" high without valve
Measured buoyancy, full, with valve, -5.8 lbs
Last hydro 5/16
Manufactured 10/05

Includes 300 bar DIN valve marked "Thermo," and stage hardware as shown. Valve was disassembled and cleaned at last hydro.

$75 as is including freight to most USA destinations
or $125 with a fresh hydro and VIP from my LDS also including freight to most USA destinations. Hydro takes approximately two weeks in addition to UPS/USPS transit time

...$50 as is...

Don't know how I missed this listing but I'm looking for a 13

I don't care about the hydro and don't really care about the valve either. I'm only going to be using it in my rinse bin to pressurize my regs as they soak. I'll probably change out the valve to a DGX " Y " valve so I can rinse my pony reg and my primary at the same time. It's never getting filled at a shop....I'll transfill from a half empty tank at 1500psi every couple of soaks. I'm diving tuesday so I'm offline. But I'll take it, let me know the payment (paypal, etc)
