Diversitech GGC-12 Gallo Gun Co2 Cartridges - pack of 12

This drain gun cartridge pack eliminates the need for air or nitrogen tanks. This 12 pack features cartridges that are environmentally safe and recyclable. Both the Drain Kat™ and the Drain Dawg™ can be used with either nitrogen or CO2. Nitrogen is easy to fill and commonly available, while a CO2 cylinder will last longer. The Drain Gun should be used only with DiversiTech brand CO2 cartridges. Drain Dawg™ and Drain Kat™ can be used for many job-site tasks. With a nitrogen fill, you can purge and pressure test copper tube, calibrate pressure controls, clean condensate lines, clean coils, inflate tires, operate air powered tools, and cleanout oil burner lines. With a CO2 fill you can do everything you do with nitrogen except purge and test copper tube or calibrate pressure controls. CO2 should never be used inside the refrigerant pipework. The Drain Dawg™ can supply up to 475psi, the Drain Kat™ can supply up to 250 psi, and the Drain Gun™ up to 800psi. Use the Drain Dawg™ when you need a continuous supply of nitrogen or CO2, Drain Kat™ when you need the a small portable 2-1/2 pound cylinder, and Drain Gun™ when you need the ultimate in hand held power.
