Since most cylinders are non-refillable, GASCO ecosmart cylinders must meet requirements set forth in the Department of Transportation’s Part 39 Regulations. Part 39 prohibits filling these cylinders with toxic gases.. The walls of a steel cylinder expand if refilled causing unstability of the gases inside.  An aluminum ecosmart cylinder is specially treated and has a thicker wall that meets DOT standards  for refilling.  It is also easy to Ship empty cylinders back to GASCO for refill at no cost to you by going to the GASCO website and printing out a FedEx no charge return label. Ecosmart cylinders cannot be taken to any other location for refill.
