Do Paintball Co2 Tanks Expire? Your Guide To Co2 Tank Lifespan

“How can I determine if my paintball CO2 tank has expired? To check the expiration date of your paintball CO2 tank, you’ll want to examine the markings on the tank itself. Typically, you’ll find a date stamp on the metal surface of the tank. Look for a four-digit code consisting of two digits representing the month and two digits representing the year of manufacture. For example, if the code reads ‘0415,’ it means the tank was manufactured in April 2015. CO2 tanks are usually good for five years from the manufacturing date, so in this case, it would be valid until 2020.”

Paintball tanks have a lifespan of approximately 15 years, but it’s essential to ensure their safety by retesting them every three to five years. This regular safety testing helps maintain the integrity of the CO2 tank and ensures it remains safe for use. So, while a CO2 tank can last up to 15 years, periodic safety checks are crucial to guarantee its reliability and longevity in the sport of paintball.
