RedRock HVAC Drain Gun Kit

Everything you need to start clearing AC condensate lines: a RedRock HVAC drain gun plus five matching unthreaded CO2 cartridges. Pressurized CO2 clears blockages instantly — no chemicals, no manual snaking.

Pick your model — the cartridges included match the gun

• 16g Button and 16g Trigger — ship with five 16g unthreaded CO2 cartridges
• 20g Button — ships with five 20g unthreaded CO2 cartridges

Button and trigger fire the same way — just the trigger style. Choose your model above.

Restock when you run low (sold separately)

• 16g guns → 16g unthreaded CO2 cartridges
• 20g gun → 20g unthreaded CO2 cartridges

Why techs carry it: one burst clears a typical 3/8"–1" condensate line — powerful, portable, and chemical-free.
