ERRECOM Extreme Ultra A/C & Refrigeration Leak Stop Cartridge 0.2 fl oz — Polymer-Free, Works with All Refrigerants (up to 6 Ton /

Errecom Extreme Ultra is a polymer-free A/C and refrigeration leak stop cartridge that safely seals small refrigerant leaks in systems up to 6 tons (21 kW).

Designed and produced in Italy by ERRECOM, Extreme Ultra is a compact, refillable leak-stopping solution compatible with all refrigerants and lubricants. The formula avoids polymers to reduce risk of blockages and component damage, and the system’s reusable delivery hardware (US patent US 11002470) makes repeat service economical for HVAC/R technicians and maintenance teams.

How does Extreme Ultra stop leaks without harming system components?

The formula is polymer-free and engineered not to react with moisture or oxygen, reducing the chance of deposits forming in expansion devices and valves. It is intended for small refrigerant leaks and should be used after confirming system suitability with a vacuum test.

• Polymer-free chemistry minimizes deposit and blockage risk.
• Safe with expansion valves (TXV, TEV), capillary tubes and Schrader valves.
• Compatible with all common refrigerants and lubricants used in HVAC/R.
• Developed in ERRECOM’s lab and OEM-approved formulations.

Will this cartridge work on my 6-ton cooling or refrigeration unit?

Yes — one 0.2 fl oz (6 mL) cartridge is formulated to treat systems up to 6 tons (21 kW). For larger systems or multiple leaks, follow manufacturer guidance and consider additional cartridges or professional evaluation.

• Treats HVAC/R systems up to 6 tons (21 kW) per cartridge.
• Best for small, localized refrigerant leaks detected during diagnosis.
• Perform a 5-minute vacuum test to confirm suitability before use.
• Refillable delivery hardware reduces long-term service costs.

How do I use Extreme Ultra with the included adapters and tools?

The cartridge ships with 1/4 SAE and 5/16 SAE adapters for straightforward connection to service fittings. Follow normal service procedures: isolate the circuit, confirm leak size with a vacuum test, attach the adapter, and inject the formulated dose per instructions.

• Includes 1/4 SAE and 5/16 SAE adapters for common service ports.
• Use with the reusable Errecom delivery device (patented system) for future refills.
• Inject only after system diagnostics and pressure checks are complete.
• Observe safety and refrigerant-handling protocols during service.

How long does the seal last and can I top up later?

Longevity depends on leak size and system conditions; Extreme Ultra is intended for stopping small leaks and for preventative maintenance. Because the delivery system is reusable, technicians can replace cartridges and top up as needed if further service is required.

• Best performance on small leaks confirmed by vacuum testing.
• Reusable cartridge system allows economical follow-up servicing.
• Ideal for preventive maintenance to reduce future leak development.
• OEM-approved formula trusted by professionals since 2001.

Who is this for: Errecom Extreme Ultra is aimed at HVAC/R technicians, commercial refrigeration service teams, and facility maintenance professionals who need a compact, safe leak-stopping option for small refrigerant leaks in systems up to 6 tons. It’s especially useful for preventive maintenance programs and for technicians who prefer a refillable, OEM-approved cartridge system backed by ERRECOM’s formulation expertise.
