The Gallo Gun is a heavy duty CO2 powered tool that quickly and easily clears condensate drain lines with 800psi of oil free air! The Gallo Gun has a strong and rugged design, built with ergonomic finger grips, and comes equipped with a flexible hose assembly and tapered fitting to fit up to a 1” drain opening. The Gallo Gun utilizes a revolutionary dual fit cartridge base that can quickly and easily fit either a 16g or larger 20g cartridge for 25% more clearing power. Features: Mag 16 16-gram CO2 cartridges How To Use The CO2 Cartridges: Place the CO2 cartridge in the dual-sized cup and start threading it on to the drain cleaner making sure the threads are starting in correct alignment. While holding the tool with the cartridge in an upright position (the tip of the cartridge facing upward), screw in until the cartridge just contacts the puncture pin, and then quickly and firmly twist it in until it stops. This will prevent loss of CO2 gas. Mak
