Leak Saver AC Flush Solvent Kit — 1 lb Pressurized (140 PSI) for HVAC Line-Set Cleaning and Compressor Burnout Residue Removal

Leak Saver AC Flush Solvent Kit is a pressurized 1 lb solvent designed to flush oils, acids, water, carbon and other residues from refrigerant line sets and refrigerant-based systems.

Built for HVAC technicians and experienced installers, this 140 PSI, 1 lb can delivers a concentrated flushing solution intended to clean central air conditioners, ductless mini-splits, packaged units, refrigerators and commercial refrigeration systems. The formula is formulated to remove common contaminants left after compressor burnouts, conversions, and component swaps. Note: a nitrogen purge is required after flushing to purge remaining solvent and debris; follow the included instruction sheet and sizing guidance for correct use.

How does this flush solvent help after a compressor burnout?

Compressor failures often leave carbon, acid, and degraded oil throughout the system; if left behind, these residues can damage replacement components. The Leak Saver formula is designed to dissolve and carry away these contaminants so downstream parts receive a cleaner environment before reassembly or recharge.

• Targets carbon deposits and acid residues left by burnouts
• Helps remove degraded oils that can harm a new compressor
• Pairs with Leak Saver Acid Scavenger for added protection
• Requires nitrogen purge after solvent flushing to clear lines

Can I use the kit for refrigerant conversions like R22 to R-410A?

Yes — the pressurized solvent is suitable for cleaning oil and impurities during refrigerant conversions and retrofits. It helps remove system oils and contaminants from line sets and components so the new refrigerant and lubricants can perform correctly.

• Effective for R22 to R-410A conversions and other retrofits
• Designed to clean line sets prior to recharging with new refrigerant
• Follow sizing recommendations to choose the right can for system tonnage
• Always complete a nitrogen purge after flushing to evacuate residues

What systems and sizes is the Leak Saver AC Flush Solvent Kit suitable for?

The 1 lb, 140 PSI can is sized to efficiently flush most residential and light commercial systems in the 2–4 ton range. It works on central air units, mini-splits, packaged systems, refrigerators and many commercial refrigeration applications when used according to the instructions and sizing chart.

• 1 lb can pressurized to 140 PSI for controlled flushing
• Recommended for systems roughly 2–4 tons (see sizing table)
• Compatible with line sets and refrigerant-based components across HVACR equipment
• Nitrogen purge remains necessary to finish the service correctly

What safety and auxiliary steps are required when using this kit?

The product is a chemical solvent in a pressurized container; users must follow the instruction sheet, wear appropriate PPE, and ensure proper ventilation. After the solvent flush, use a nitrogen flush kit to purge the lines and prevent solvent and debris from remaining inside the system.

• Read and follow the included instruction sheet for proper procedure
• Use personal protective equipment and maintain ventilation
• Complete a nitrogen purge after flushing to evacuate solvent and contaminants
• Keep solvent cans upright and store per label directions

Who this product is for: experienced HVAC technicians, service contractors, and trained refrigeration specialists who perform compressor replacements, refrigerant conversions, line set cleanings and component swaps. This kit is intended for professionals who understand nitrogen purging and follow safety procedures; it is not a consumer-level cleaning spray and should be used alongside proper HVAC service tools and training.
