Giant CO2 offers hydrostatic testing and certification. All of our hydro-testing is performed by Orange County Cylinder Requalification (OCCR) and is available for residential, commercial, and industrial tanks.

​

A hydrostatic test, or "hydro-test," verifies that a tank is in good condition and able to withstand the pressure of holding compressed gas. Whether for personal, commercial, or industrial use, the California DOT (Department of Transportation) requires that all aluminum and steel cylinders used for compressed gas pass a hydrostatic test every five years. If a tank's hydrotest date is past the five years, it is illegal to refill the bottle until it has been tested. To check if your tank is due for recertification, check the date stamped near its neck. Requalification is also recommended anytime that the cylinder's integrity is suspect (such as after it has been dropped, exposed to excessive heat, left unused for a few years, or has excessive rust or corrosion).

       

If your tank passes the test, we’ll requalify and re-stamp it, certifying it for another five years. Once it has been requalified, it is ready to be filled. Upon request, we can fill it with CO2, Nitrogen, or Beer Gas before returning it to you. Payment is required upfront; we accept all major credit cards.
