MR CARTOOL AC Flush Kit with 220 PSI Gauge 3.5 ft Nylon Hose for R134A/R12, Stainless Steel Bottle

MR CARTOOL AC Flush Kit is a portable HVAC flushing system with a 220 PSI dual-scale gauge and 3.5 ft nylon hose for cleaning R134A and R12 air conditioning lines before compressor replacement or system upgrades.

This stainless-steel flush bottle and accessory set is built for automotive, domestic and light commercial refrigeration service. It is engineered to remove residual oil, metal particles and compressor debris from refrigerant lines and evaporators so new compressors and components can operate in a cleaner environment. The kit requires an external air compressor and appropriate cleaning solvent, and is compact for shop or mobile use.

How does the MR CARTOOL AC Flush Kit remove contaminants?

The kit uses pressurized air to push cleaning solvent through the A/C lines, carrying out oil, sludge and metal shavings that accumulate over time. A conical rubber tip and tight fittings prevent backflow and ensure solvent flow through targeted sections.

• Stainless-steel flush tank holds cleaning solution securely.
• Conical rubber sealing tip prevents return flow into the bottle.
• Brass fittings resist corrosion where solvent contacts metal.
• Air-driven flushing clears lines quickly compared with manual methods.

What pressure ratings and safety features are included?

The unit incorporates a dual-scale pressure gauge showing 0–220 PSI (0–16 bar) so you can monitor flushing pressure at a glance. An integrated air relief valve vents excess pressure automatically for safer operation when pump or source pressure spikes.

• Dual-scale gauge for PSI and bar readings.
• Working hose pressure rated at 500 PSI; maximum burst 2500 PSI.
• Air relief valve prevents over-pressurization during use.
• Nylon hose offers heat resistance and flexibility under load.

What accessories and build materials does the kit include?

The flush kit pairs a sturdy stainless-steel bottle with brass connectors and a nylon hose designed for long service life. All parts that contact solvent are made from materials chosen to reduce corrosion and withstand mechanical stress during repeated shop use.

• 3.5 ft nylon hose for reach and pliability in tight engine bays.
• Stainless-steel flushing tank for durability and solvent compatibility.
• Brass fittings for chemical resistance on connection points.
• Conical rubber tip and secure connectors for leak-reduced operation.

How simple is the kit to operate for routine AC maintenance?

Operation is straightforward: add a light A/C cleaner to the bottle, attach the connector and seal the tip, then connect to an air compressor and open the valve to force solvent through the system. The compact size keeps setup and storage easy for both professional technicians and experienced DIYers.

• Fill flush bottle with recommended solvent (not included).
• Attach fittings, seal the conical tip, and connect to compressor.
• Open valve and flush lines; the gauge monitors working pressure.
• Lightweight and compact for shop benches or mobile tools.

Who is this for: The MR CARTOOL AC Flush Kit is aimed at mechanics, HVAC technicians and knowledgeable DIYers who service R134A and R12 systems and want a reliable, portable flushing solution. It is suited for pre-compressor replacement cleaning, system conversions or routine line maintenance where removing oil, sludge and particulate will improve component longevity and help ensure a cleaner refrigerant circuit. Note: cleaning solvent and an air compressor are required but not included; always follow solvent manufacturer and safety guidelines when flushing refrigerant lines.
