As long as it hasn't been contaminated by someone pumping something else into it you should be all set unless the tank corrodes or the valve leaks, you should be good as long as the gas stays inside. I'm glad this stuff doesn't go bad because there's a 30# container of Dupont Freon22 that I expect will continue to increase in value over time until/unless people stop using R22 as these systems become less common as they get replaced with other units or people start using more retrofit refrigerants but I figure the market will remain there unless the EPA decides to outlaw its use and require a retrofit refrigerant or system replacement.
