YUANRI 1L Stainless Steel A/C Flush Kit for Automotive & Home HVAC — Reinforced Hose, Pressure Gauge

YUANRI's 1L stainless-steel A/C flush kit is a heavy-duty flushing canister system designed to safely and effectively rinse automotive and home air conditioning lines and components.

Whether you're performing maintenance on a car evaporator, replacing an HVAC section, or cleaning household air conditioner ducts, this kit gives you a portable pressurized canister, reinforced hose, and adapters built for refrigerant-system compatible cleaning. The unit is built from thickened stainless steel for corrosion resistance, uses a braided PVC hose rated for high pressure, and includes a pressure relief valve for safer operation. An air compressor is required to pressurize the canister (not included).

How does this canister safely handle high-pressure flushing?

The YUANRI canister is engineered with thicker stainless steel walls to resist corrosion and hold pressure more reliably than thinner metal bottles. A reinforced PVC hose with fiber braiding prevents expansion and bursting under load while fittings and spare seals reduce leak risk.

• 1000 ml stainless steel canister with reinforced construction
• PVC hose with fiber-braid liner rated to 600 PSI working pressure
• Included pressure gauge and adjustable relief valve for controlled venting
• Replacement O-rings and gaskets to maintain airtight seals

Which systems and refrigerants can I use this flush kit on?

This flush kit is compatible with most common A/C service tasks across automotive and home HVAC applications. It is intended for mechanical flushing and cleaning of pipes, evaporators, condensers, and ducts and can be used where solvents or flushing liquids are applied, provided you follow compatible-chemical guidance.

• Suitable for vehicle evaporators, condensers, and fuel-line cleaning
• Works for household air conditioners and refrigerator service lines
• Designed to be used in systems running R134a, R12, R22, R404, R410A (follow chemical compatibility)
• Not a refrigerant charging device—air compressor required for pressure

What controls and accessories are included to make flushing easier?

The kit ships with a selection of fittings and spare seals so you can adapt to common service ports and minimize downtime from lost parts. A built-in gauge and an adjustable safety relief valve allow you to set working pressure levels and release excess pressure automatically when needed.

• Pressure gauge and 1/4" SAE hose adapter for system hookup
• Flush head with rubber tapered tip to access tubes and openings
• Extra adapters, rubber O-rings, and plastic gaskets included
• Adjustable relief valve: tighten to raise relief, loosen to lower (do not exceed recommended working pressure)

How should I prepare and use the kit for best results?

Always inspect seals and fittings before pressurizing and choose a flushing solvent compatible with the system's materials. Connect the canister to an air compressor, set the working pressure below the recommended maximum, and flush until lines run clear; then allow components to vent and dry before reassembly or refrigerant service.

• Check spare O-rings and gaskets; replace if worn
• Use a hex key to adjust the relief valve; never exceed 150 PSI working pressure
• Rinse until debris and solvent runoff are clear; fully vent and dry lines afterwards
• Compressor required but not included—use appropriate pressure-rated compressor

Who is this for: technicians and knowledgeable DIYers who perform maintenance or repair on vehicle A/C systems, household air conditioners, refrigerators, or other ducted equipment. It's especially useful when replacing components, performing deep cleans, or preparing systems for repairs where removing oil, sludge, or particulate is necessary. If you need a durable, pressure-rated flushing canister with multiple adaptors and safety features, the YUANRI 1L A/C flush kit is built for those tasks. Follow safety protocols and chemical compatibility instructions when selecting cleaning fluids and always use a suitable compressor to pressurize the unit.
