It is normally supplied as a nonliquefied compressed gas in high-pressure DOT 3A or 3AA cylinders at or above a pressure of 1800 psig at 70 F. Helium can be condensed into a cryogenic liquid when refrigerated to below its normal boiling point of -452.1 F, the lowest boiling point of any substance known.
