ERRECOM Extreme Ultra A/C Leak Stop 0.2 fl oz Cartridge — Reusable Easy Inject for R32 & R410a, up to 6 Ton Systems

ERRECOM Extreme Ultra is a 0.2 fl oz (6 mL) reusable Easy Inject cartridge that permanently seals small refrigerant leaks and adds UV dye for diagnostics in HVAC/R systems up to 6 tons with a 5/16" charging port.

This compact, polymer-free leak stop was formulated by ERRECOM to repair small refrigerant leaks in air conditioning and refrigeration systems, compatible with both R32 and R410a. The system is supplied in a patented Easy Inject delivery device that can be reused—only the cartridge is replaced—making it cost-effective for technicians and preventive-maintenance programs. Use it after verifying the system’s suitability with a quick vacuum test and follow charging-port instructions for a clean, controlled injection.

How does Extreme Ultra stop refrigerant leaks without harming system parts?

The formula is free of reactive polymers and is designed not to react with moisture or oxygen, reducing the risk of internal blockages. It acts on both rubber and metal components and is compatible with expansion devices and Schrader valves when used as directed.

• Polymer-free chemistry to avoid clogging TXVs, TEVs and capillary tubes
• Works with all common compressor lubricants
• Safe for rubber seals and metal fittings when used per instructions
• Includes UV dye to find remaining leaks during inspection

Can I use this cartridge for preventive maintenance or only for active leaks?

Extreme Ultra is suitable for both repairing active small leaks and for preventative maintenance to reduce the chance of future seepage. Technicians often add it during routine service to protect vulnerable joints and elastomers before failures develop.

• Ideal for scheduled maintenance on residential and light-commercial systems
• Helps deter future tiny leaks by conditioning seals and interfaces
• UV dye assists in routine leak-detection checks
• One universal 0.2 fl oz dosage covers systems up to 6 tons (21 kW)

Which systems and refrigerants are supported by this Easy Inject solution?

The product is engineered for HVAC/R systems that accept a 5/16" charging port and works with modern refrigerants like R32 and R410a. It is suitable across a wide range of equipment, from residential split systems to commercial chillers and heat-pump installations within the specified tonnage.

• Compatible with R32 and R410a refrigerant systems
• Fits systems up to 6 tons (21 kW) or with up to 24 fl oz (700 mL) compressor oil
• Appropriate for air conditioners, refrigeration units, heat pumps and geothermal systems
• Delivered through a reusable US-patented Easy Inject device (US 11002470)

What are the steps and checks before using Extreme Ultra?

Always perform a brief vacuum test to confirm the leak is the right type and size for a stop-by-inject solution. Follow the Easy Inject instructions, inject at the 5/16" charging port, and then inspect with UV light to verify sealing and locate any remaining leaks.

• Conduct a 5-minute vacuum test to assess suitability
• Attach to the 5/16" charging port and inject as directed
• Use UV light post-injection to confirm repair and find other issues
• Replace only the cartridge for future applications to save costs

Who is this for: ERRECOM Extreme Ultra is made for HVAC/R technicians, service contractors, building maintenance teams, and facility engineers who need a compact, reusable injection solution for stopping minor refrigerant leaks and performing preventative care. It’s especially useful when working on systems with a 5/16" charging port using R32 or R410a refrigerants and where avoiding polymer-based sealants is important for system reliability.
