Leak Saver CO2 Refill Cartridges 8-Pack – Refrigerant‑Grade CO2 for Leak Shot, A/C & Refrigeration

These cartridges are manufactured to work with the Leak Shot HVAC kit (sold separately) and provide a clean, professional source of high‑pressure CO2 that won’t introduce contaminants into cooling systems. Built and specified by HVAC technicians, the eight‑pack is intended for use on systems up to 5 tons and pairs with Leak Saver Direct Inject sealant for targeted leak repair and condensate drain clearing.

How does this refill pack work with my Leak Shot HVAC tool?

The cartridges contain refrigerant‑grade CO2 at high pressure and thread into the Leak Shot HVAC tool to provide the burst of gas needed for line clearing and pressurization. They are sized and rated to meet the tool’s operating requirements so you get consistent performance each time.

• Eight prefilled cartridges per pack for repeated use
• Threaded connection compatible with the Leak Shot HVAC (tool sold separately)
• Refrigerant‑grade CO2 minimizes contamination risk
• Designed to deliver the pressure profile required for condensate and leak operations

Can these cartridges help locate or seal refrigerant leaks?

Used with the Leak Saver Direct Inject sealant (sold separately), the CO2 cartridges allow safe pressurization and delivery of sealant into the system to help isolate and treat leaks. The cartridges themselves provide the working pressure for injecting sealant or for performing targeted pressure tests.

• Enables pressurizing systems up to 5 tons for leak testing
• Works in tandem with direct inject sealant for spot repairs
• Noncontaminating CO2 protects system components during the process
• Useful for pinpointing leaks by allowing controlled pressurization

What maintenance or safety steps should I follow when using these cartridges?

Follow the Leak Shot HVAC tool instructions and standard HVAC safety procedures when handling high‑pressure CO2 cartridges. Store cartridges in a cool, dry place, avoid exposure to direct sunlight, and use eye and hand protection during installation and operation.

• Wear appropriate PPE—gloves and eye protection—during use
• Do not expose cartridges to temperatures above manufacturer recommendations
• Securely attach cartridge to the Leak Shot HVAC before actuation
• Dispose of spent cartridges per local hazardous waste guidelines

How many systems or jobs will this 8‑pack typically cover?

Coverage varies by task—clearing condensate lines often consumes less CO2 than pressure testing and injecting sealant—so one cartridge may suffice for small jobs while larger repairs can require multiple cartridges. Professionals keep packs on hand to ensure they have enough cartridges for several small jobs or a handful of larger repairs.

• One cartridge can clear drains or perform small pressurizations
• Larger systems or multiple injection steps may use several cartridges
• Designed for compatibility with systems up to 5 tons
• Eight cartridges provide backup supply for repeated service calls

Who is this for: HVAC technicians, service contractors, and informed DIYers who already own the Leak Shot HVAC tool and need a reliable source of refrigerant‑grade CO2 for condensate clearing, pressure testing, and assisting with direct inject leak repairs. These cartridges suit field professionals who want technician‑grade consumables they can depend on for consistent, contaminant‑free performance.
