These are eight refrigerant‑grade CO2 cartridges made as the refill for the Leak Shot HVAC kit, designed to power condensate line clearing and direct‑inject leak sealing in A/C and refrigeration systems.

Designed by HVAC technicians, the Leak Saver Leak Shot CO2 refill cartridges supply high‑pressure, system‑safe CO2 to operate the Leak Shot HVAC tool (sold separately). They are manufactured for use in residential and light commercial HVAC and refrigeration work, compatible with systems up to 5 tons. The cartridges are formulated and handled to avoid contamination while enabling condensate drain unclogging and facilitating direct‑inject leak sealant operations.

How do these CO2 cartridges work with the Leak Shot HVAC kit?

The cartridges deliver a measured burst of high‑pressure CO2 to drive the Leak Shot tool’s functions: blowing out condensate clogs and creating pressure for applying the Leak Saver Direct Inject sealant (sold separately). Because they’re refrigerant‑grade, they won’t introduce oils or contaminants that could harm system components. Each cartridge is single‑use and installs quickly in the Leak Shot charger for fast on‑site operation.

  • Eight cartridges per pack for multiple service calls or repeat jobs
  • Refrigerant‑grade CO2 minimizes contamination risk
  • Compatible with Leak Shot HVAC charger and fittings
  • Suitable for systems up to 5 tons

What problems can these CO2 refills help solve?

These refills enable two common HVAC tasks: clearing clogged condensate drain lines and assisting in direct‑inject leak sealing. Clearing drains reduces overflow and water damage risks, while pressurizing a circuit makes it easier to introduce the Leak Saver Direct Inject sealant at the leak site. They are not a substitute for full system diagnostics but speed repairs and reduce repeat visits when used properly.

  • Rapid condensate line clearing to restore normal drainage
  • Provides pressure to apply direct‑inject leak sealants
  • Useful for quick troubleshooting and temporary repairs
  • Designed to avoid residue that could obstruct components

Are these cartridges safe and compatible with my system?

When used with the Leak Shot HVAC tool and following manufacturer instructions, these refrigerant‑grade CO2 cartridges are made to avoid introducing contaminants and are compatible with A/C and refrigeration systems up to 5 tons. Always follow safety protocols for high‑pressure gas cartridges, verify tool compatibility, and confirm the repair method is appropriate for the specific system and leak type. Do not attempt procedures outside your scope of training.

  • Engineered to avoid oils and residues that damage systems
  • Rated for residential and light commercial systems up to 5 tons
  • Use only with Leak Shot HVAC tool and recommended fittings
  • Follow all safety and handling guidelines on the product label

How many cartridges will I need for routine jobs?

The eight‑pack is sized for technicians who perform multiple service calls or for homeowners who want several refills on hand. Typical drain‑clearing and single leak‑seal operations often use one cartridge each, but usage depends on job complexity. Keeping an 8‑pack stocked reduces downtime between visits and ensures you have compatible cartridges when the Leak Shot HVAC kit is in use.

  • One cartridge often suffices for a single drain clear or seal attempt
  • Eight cartridges provide supplies for multiple jobs or repeat attempts
  • Ideal for professionals or prepared homeowners with a Leak Shot kit
  • Store unopened cartridges per the manufacturer’s temperature and pressure guidance

Who is this for: HVAC technicians, refrigeration service professionals, and informed homeowners who already own or plan to use the Leak Shot HVAC tool and want refrigerant‑grade CO2 refills that are made to industry handling standards. These cartridges support quicker condensate maintenance and help facilitate direct‑inject leak‑sealing workflows; they are intended for trained or instructed users following safe, recommended procedures.
