ERRECOM Refrigerant Leak Stop for Refrigerators — 6 mL Cartridge, R600/R290/R134a Compatible, 1/4 SAE Adapter

ERRECOM Extreme Ultra White is a compact, professional-grade 6 mL cartridge that permanently seals small refrigerant leaks (up to 0.3 mm) in hermetic compressors using R600, R290, or R134a.

This product is formulated and manufactured in Italy for technicians who need a fast, targeted solution for minor leaks in refrigerators. The cartridge is designed for safe insertion into systems with hermetic compressors and comes with a 1/4 SAE adapter for straightforward connection. It works on both rubber and metal components and can also be used as a preventative measure to reduce future seepage.

How does ERRECOM Extreme Ultra White stop leaks in refrigerators?

The cartridge releases a sealing compound that travels to the leak site and solidifies, creating a long-lasting seal for pinpoint and small hairline defects. It is optimized for hermetic compressor systems and compatible with common household refrigerants.

• Seals leaks up to 0.3 mm in diameter
• Formulation flows through refrigerant lines to reach the breach
• Suitable for both rubber gaskets and metal fittings
• Works with R600, R290 and R134a systems

Is it easy and safe to use for a technician on-site?

Yes—ERRECOM packed the sealing solution into a 6 mL cartridge to allow precise dosing and safe handling. The included 1/4 SAE adapter simplifies connection to service ports, reducing mess and speeding up repairs.

• 6 mL cartridge for controlled insertion
• 1/4 SAE adapter for common service fittings
• Minimizes product waste and exposure during service
• Designed for professional use and field conditions

Which refrigerants and components are compatible?

This formulation is specifically developed for R600 (isobutane), R290 (propane) and R134a systems and works on the typical materials found in refrigeration circuits. It performs on rubber seals and metal joints commonly found in domestic and light-commercial refrigerators.

• Compatible with R600, R290 and R134a refrigerants
• Works on rubber hoses, O-rings and metal fittings
• Best suited for hermetic compressors and sealed systems
• Not intended for large-scale or non-hermetic HVAC systems

How long does the repair last and when should I call a service technician?

The product is engineered to provide a permanent seal for small leaks when applied correctly, but performance depends on leak size and system condition. For recurring leaks, larger breaches, or when the system requires recharge or component replacement, a full professional service visit is recommended.

• Permanently seals leaks up to 0.3 mm when properly applied
• May not fix large cracks, corroded components, or failed compressors
• Use as part of preventive maintenance or first-response repair
• Consult a technician for repeat leaks or major system work

Who is this for: ERRECOM Extreme Ultra White is aimed at refrigeration professionals and trained service technicians who need a precise, small-volume repair tool for domestic and light-commercial refrigerators with hermetic compressors. It is ideal for jobs that require a compact cartridge, quick connection via 1/4 SAE adapter, and compatibility with R600, R290 and R134a systems; it is not a substitute for full-system overhauls or large-scale HVAC repairs.
