*A TR21.4 Can Taper is required to dispense the gas.
(1) R744, 12 Oz. High Pressure Cylinder
Carbon Dioxide (CO2)
****DESIGNED FOR SYSTEMS THAT USE R744 REFRIGERANT ONLY!!
Please note that CO2 should never be charged in liquid form when the system is at a lower pressure than the triple point (5.2 bar).
If you were to do so, the liquid entering the system would suddenly change state, turning into dry ice and remaining in that state inside the system.
