The hydro date is the number on your tank that tells you when your tank must be hydro tested (usually 5 years). Hydro testing is when you ship your bottle away to make sure it is still suitable to fill with pressure. 9oz tanks do not need to be hydro tested, or any other tanks with a diameter of less than 2 inches.
"Hydro" is short for Hydrostatic Testing. After so many years (listed on each tank) a propellant tank must be retested for leaks and material strength. If it fails, it is condemned and cannot be refilled, if it passes, you may use it until the next test date, which will be engraved onto the bottle. Hydro testing can be done by either physically going to and ordering, or mailing your tank to the manufacturer.
