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
