Errecom EXTREME ULTRA (6 mL) is a polymer-free leak stop that permanently seals micro-leaks in HVAC/R systems. It’s made for licensed techs who want fewer call-backs, faster sign-offs, and a clean system—no clogs, no dramas. Fair dinkum, it just works.

Key Features & Trade Benefits

• Seals micro-leaks up to 0.3 mm → Fix the sneaky leaks that waste gas and time.
• Universal 6 mL dose → One cartridge treats systems up to 21 kW (6 tons) or ~700 mL oil—easy stocking for vans.
• Polymer-free & non-reactive → Won’t react with oxygen or moisture and won’t gum up TXVs or small passages.
• Works with all refrigerants → CFC, HFC, HCFC, R32, HFO—mixes with common lubricants.
• Service-friendly → UV-visible for post-repair checks; not flammable or irritant—operator-safe.
• Quieter running → Helps reduce compressor noise in borderline systems.

Why This Product Matters

Real-world: rooftop split, 40-degree heat, charge keeps drifting and the electronic detector’s teasing you. A tiny pinhole is bleeding charge. One EXTREME ULTRA dose, leak sealed, vacuum confirmed, and you’re back to target pressures. Customer’s stoked and you’ve dodged a come-back—she’ll be right.

Pro Tip

Always find the leak first, then seal. Use an electronic detector to locate the area, verify with bubbles, repair where practical, then add EXTREME ULTRA. For compliant practice and A2L/R32 safety, follow AIRAH’s Refrigerant Handling Code of Practice and relevant AS/NZS standards.

FAQs

Will this work with R32/A2L systems?

Yes—EXTREME ULTRA is compatible with R32 and HFO blends. Always follow your risk controls and the TDS when injecting into A2L systems.

Does it clog TXVs or cap tubes?

No. The formula is polymer-free and non-reactive to oxygen or moisture, so it doesn’t form sludge that could block small passages.

How do I size the dose?

One 6 mL cartridge treats up to 21 kW or about 700 mL of oil. Larger plants may require multiple cartridges per the TDS.
