Understanding the crucial difference between the gas's stability and the physical tank's service life is key to answering how long do oxygen tanks last before they expire.

While the oxygen gas itself is stable and doesn’t technically expire, the usability of a tank diminishes over time. For those asking **how long are unused oxygen tanks good for**, the answer depends on the manufacturer's purity guarantee for the gas and the structural integrity of the cylinder itself.
