How Do You Check The Hydro Date Of A CO2 or Compressed Air Tank?
Paintball air tanks are required by the government to be hydrostatic tested every few years to ensure they are structurally sound and safe for use. The life of air bottles used for paintball purposes can be measured by their hydro test date. Most modern air bottles must be tested every five years. The date at which this must happen can be determined by checking the bottle for information printed on it or stamped into it. CO2 bottles and aluminum compressed air tanks have a date, in month and year, stamped into them near the valve at the top, while an information label is printed into the side of each carbon fiber compressed air bottle, also with a month and year. Hydro testing must be performed within five years from the date found on the bottle. Once tested, the bottles will either be re-certified for another five years of use, or will be rendered unusable should a reason be found not to approve them such as visible damaged.
