  • Quality up most and then value.
Good product at great price. Would definitely recommend.

  • Quality tank. Came full as advertised.
Fed-X delivered it on the valve, but valve and cap were all in place and worked properly. Nice clean, quality tank. 2200 at room temp in the air-conditioned shop. Great purchase. Especially if you rarely need refills and want something nice for the home shop. Likely pick up a C25 and maybe helium mix as well. ... show more

  • Nice New Cylinder...???Underfilled???
I like having been able to order a 125 cu ft tank of Ar from Amazon, rather than driving to my local Airgas store, hoping that they'd have one in stock. The cylinder I received was totally new & shiny, pressure tested 4/24. DOT 3AA stamped, tested to 2265 PSI. On receipt, the tank tested at only 1800 PSI. YES, I tested it at 42 °F, which should result in a pressure of about 1900 PSI. In any case, these tanks are definitely not overfilled. NOW I can start playing around at home with my spiffy new TIG welder. ... show more

Awesome deal! Brand new tank and a fraction of what my local supply place would charge for a used tank. I highly recommend!
