Errecom Extreme Ultra | A/C Leak Stop for HVAC/R and Vehicle A/C

The Errecom Extreme Ultra is a specialized sealant designed to resolve small refrigerant leaks in both HVAC/R equipment and vehicle air conditioning systems. It provides an accessible solution for technicians and vehicle owners aiming to fix minor losses in cooling performance without replacing major hardware.

A core benefit of this treatment is its polymer-free composition. Because it does not react with moisture or oxygen, it will not form solid clogs inside your system. This keeps sensitive components running smoothly, including expansion valves such as TXVs, TEVs, capillary tubes, and standard Schrader valves. It can also be introduced proactively during regular maintenance to prevent leaks before they begin.

Application efficiency is supported by a US patented reusable delivery format (US 11002470). Once you have the initial setup, you only need to acquire replacement cartridges for subsequent jobs, which reduces ongoing maintenance costs. The formulation itself is developed and produced in Italy, backed by chemical testing and OEM use dating back to 2001.

Keep in mind that this product is strictly formulated for minor leaks. To ensure the treatment will hold, the manufacturer requires performing a 5-minute vacuum test beforehand to verify the leak size is within repairable limits. It is not intended for large punctures or structural blowouts.

Verdict: Errecom Extreme Ultra is an excellent choice for anyone needing a safe, non-clogging fix for minor refrigerant loss in automotive or building A/C systems. If your system passes the preliminary vacuum test, this reusable solution offers dependable protection for delicate cooling components.

A great fit if you:

• Need to seal small refrigerant leaks in a vehicle or HVAC/R system.
• Want a non-reactive, polymer-free formula that will not clog expansion or Schrader valves.
• Plan to perform preventative maintenance to stop future leaks.
• Prefer a reusable applicator setup that accepts refill cartridges.

Consider something else if you:

• Have a large, severe leak that fails a 5-minute vacuum test.
• Are unable to run a vacuum test on your system prior to application.

How do I know if my system leak can be fixed by this product?
You should perform a 5-minute vacuum test on your system to ensure the leak is small enough to be repaired with Extreme Ultra.

Will this formula clog my air conditioning components?
No. The polymer-free formula does not react with oxygen or moisture, protecting components like capillary tubes, TXVs, TEVs, and Schrader valves from blockages.

Can I reuse the applicator?
Yes. The delivery system is patented in the US (US 11002470) and can be reused by simply attaching a new replacement cartridge for future jobs.
