Yonligonju AC Flush Kit — Automotive A/C Pipeline Cleaning Set, Stainless Canister & 220PSI Gauge

Yonligonju AC Flush Kit is a professional-grade, reusable tool set for flushing and cleaning automotive air conditioning pipelines safely and efficiently.

This compact kit bundles a high-capacity stainless steel canister, pressure gauge, corrosion-resistant fittings, and a durable steel spray gun so you can purge refrigerant oil, debris, and contaminants from R134A, R12, R22, R404, and R410A systems. Built for repeated workshop use, the design emphasizes safe relief control, clear pressure monitoring, and reduced spray-back to speed service while protecting compressors and system components during replacement or maintenance.

How does this kit remove oil and contaminants from an AC line?

The canister pressurizes with shop air to propel a chosen flush solvent through the system, dislodging sludge, varnish, and residual oil. The upgraded spray gun and nozzle minimize return flow so expelled fluids and particulates exit the system rather than re-circulate.

• Large-capacity stainless can withstand multiple flush cycles
• Steel spray gun with improved nozzle for steady, directed flow
• Air fittings compatible with R134A, R12, R22, R404, R410A service ports
• Simple pressurize-and-spray operation — no special tools required

Is it safe to use in a busy shop or home garage?

Safety features reduce risks when working under pressure: a readable 220PSI gauge helps you monitor bottle pressure in real time, and the built-in air relief valve opens automatically if pressure crosses a safe threshold. Metal joints and a corrosion-resistant ball valve provide tight seals to prevent leaks during use and transport.

• 220PSI gauge for accurate, instant pressure readings
• Automatic air relief valve prevents over-pressurization
• Metal ball valve and corrosion-resistant fittings for leak control
• Thickened tank walls endure shop conditions and repeated use

Which vehicles and refrigerants are compatible with this flush kit?

The Yonligonju kit is designed for light-duty automotive A/C systems and supports common refrigerants used in passenger and light commercial vehicles. It works with pressurized flushing agents intended for HVAC system cleaning and handles conversion and compressor-replacement service routines.

• Supports R134A, legacy R12, R22, R404, and R410A applications
• Suitable for compressors, evaporators, condensers, and piping
• Accepts typical shop flush solvents and pressurized air mixes
• Reusable for multiple vehicles—ideal for small fleets or garages

How do I maintain and store the kit to extend its life?

After each use, purge remaining solvent, blow out lines with clean compressed air, and wipe down metal surfaces to prevent corrosion. Store the canister upright in a cool, dry area and check seals and hoses before every job to preserve performance and safety.

• Drain and air-blow hoses and gun after flushing
• Inspect O-rings, fittings, and the pressure gauge routinely
• Keep the tank upright and away from direct heat sources
• Replace worn hoses or seals to avoid leaks and pressure loss

Who is this for: Yonligonju AC Flush Kit is built for professional technicians, independent mechanics, and knowledgeable DIYers who perform A/C system repairs or compressor swaps. It’s best suited to shops that handle diverse refrigerants or anyone needing a durable, reusable flushing solution with clear pressure control and added safety features.
