Medical Oxygen Cylinders - Industrial Pressure Testing Ltd.- composition of gas in medical oxygen cylinder expiration cycle results in water ,Medical Oxygen has an expiry period of three years. Cylinder test periods and medical oxygen periods must be kept in line. Here are some examples. Examples: Cylinder retest date 2008/06 (June 2008) The oxygen expiry date will be one year only as it must be kept in line with the next retest date of the cylinder. Cylinder retest date 2010/06 ...Does medical grade oxygen in a steel cylinder have a shelf ...Nov 24, 2012·Cylinders filled to FDA requirements, like medical grade O2, are assigned lot numbers for tracking and expiration dates. Therefore, yes, it does expire. Doesn't mean the gas actually goes bad, just means it must be emptied and refilled. I believe they are good for 5 years. Roger
