Can you refill an expired propane tank
Updated October 24, 2026
No refill station will fill a cylinder that is past its requalification date. Exchange cages will take it. Here is how to read the date and what to do about it.
Reading the date
Look at the steel collar around the valve. A stamp such as “06 19” means the tank was made in June 2019. From that date a cylinder is good for 12 years. A tank made in June 2019 can be refilled through June 2031.
After the first 12 years the tank has to be requalified by a certified facility. A requalified tank gets a new stamp with the month, year and the requalifier’s mark, often followed by “E” for an external visual inspection. That stamp is good for 5 more years.
What a refill station does
The attendant checks the collar before connecting the hose. An out-of-date tank is refused. Other reasons for refusal:
- No OPD valve. Tanks made before 2002 may have a round or star-shaped handwheel instead of the triangular OPD wheel. They cannot be refilled.
- Dents, deep rust, a damaged foot ring or a bent valve guard.
- A valve that does not seal.
Your options with an expired tank
- Exchange it. Blue Rhino, AmeriGas and other exchange programs accept expired tanks and tanks with old valves. You pay the normal swap price. The finder lists cages near you.
- Get it requalified. Some propane dealers do this for a small fee if the tank is in good shape. Call before you drive; most of the dealer offices in the station list can tell you whether they offer it.
- Recycle it. A hardware store or scrap yard that handles cylinders can take it. Do not put a cylinder in household trash or curbside recycling.
If you plan to keep refilling
Buy a tank with a recent date stamp, keep it out of the weather so the steel stays clean, and note the month it expires. Every refill after that date means an exchange instead.
