You can use this primary regulator on any CO2 tank with a CGA-320 valve. CO2 tanks have a male thread (CGA-320); these regulators have a female thread. This regulator features dual gauges to measure PSI as well as the volume of CO2 in the cylinder, indicating how much CO2 is left in the cylinder and when you should have it refilled. The knob on the front is used to adjust the output pressure.
