Propane tanks are pretty tough since they’re built to safely store pressurized gas outdoors and exposed to the Texas elements… but even the best built tank has a shelf life, so every so often should be looked over. That way you can inspect it for signs of weakness or deterioration.

How long are propane tanks good for?


In the United States, a bottle is usually good for 12 years from the date of manufacture. A recertified propane tank is good for 5, 7, or 12 years, depending on the method and type of recertification.

How do I know if my propane tank is expired?


The easiest way to tell if your propane tank is expired is to simply check the area around the collar or handle. It should be stamped with the date the tank was manufactured or last certified. That should give you a good idea of how much longer the tank has on it’s lifespan. If you have any questions or concerns, you can always call us at 512-913-7695 . We can help walk you through it.

How to read the markings on your propane tank

If you look near the handle of your propane tank, you’ll notice some stamped markings in the metal. These give you all the information you need regarding your tanks capacity rating, and certified date. If you look closely, you should see the date it was manufactured stamped near the valve. It should reads in the standard month and year format. If your tank was built in January of 2018, it would read 01-18.

Your tank is also stamped with a unique identification, similar to the VIN number on most cars. This helps the United States DOT (Department of Transportation) and propane dealers to track and keep safety records for every tank out there.

You might also see a requalifier’s identification stamped into the handle area of your tank. Once you know the manufacture or recertification date, you’ll be able to determine how close the tank is to reaching its expiration date.

Where do I find my propane tank’s recertification date?


A propane tank’s recertification date is usually referred to by a letter instead of a number. The letters A, B, C, and D, correspond with a quarter of the calendar year. The letter “B” would mean the tank had been recertified in March, April, or May, followed by the two numbers of the year. In this case, a tank stamped with “B 18” would indicate the second quarter of 2018.

What should I do when my propane tank is expired?

A tank nearing its expiration date should be recertified or removed from circulation. A qualified service technician trained to property inspect and qualify tanks is required for this process. If your tank is getting close to it’s expiration date, it’s best to swap it out for a new tank. Should you need a new tank, we have 120 and 250 pound tanks in stock.
