Draeger Tubes have a shelf life of 2 years. To see your Draeger tubes expiration date, check the box your tubes were shipped in, because the expiration dates are stamped on the sides of the boxes when they are shipping out.
The Natural Gas Draeger Tube is the only exception to the two year shelf life rule. The Natural Gas tube has a shelf life of one year.
