Why Do Propane Tanks Expire?

Written on: October 6, 2020

propane cylinderSpring will be here before you know it. That means blooming flowers, more time outdoors, and of course, grilling.

But there are a few things you should know about your grill’s propane tank before you fire it up for the season.

Take a good look at the date stamped on the top of the tank. That’s the year your tank was certified. Propane suppliers will not fill your tank if it has been certified more than 12 years ago.


It’s a safety measure. Old tanks may have leaks, rust, punctures or other safety hazards. Plus, expiration dates ensure that your tank has the latest valve safety update.

What are my options?

If your tank is expired, you have two options. Depending on the tank, its safety features and the date of initial certification, you may be able to get it recertified. This extends its expiration date for another five years.

If your tank cannot be recertified, there’s no need to worry. Lakes Gas’ tank exchange program makes getting a new tank easy. Just bring it to your nearest Lakes Gas location. We also have Swap and Go cabinets at many area gas stations.
