YUANRI AC Flush Kit 1L Stainless Steel Canister — Portable A/C Flush Tool with Pressure Gauge & Relief Valve

YUANRI AC Flush Kit is a 1-liter stainless-steel pressurized canister set designed to safely flush and rinse residential and automotive air conditioning lines, evaporators, condensers and ducts.

If you need a durable, portable solution to clean refrigerant lines, evaporators or household A/C coils before repairs or retrofits, this flush canister kit combines a thickened stainless bottle, reinforced hose and adjustable relief valve so you can control flow and pressure. The kit works with common refrigerant systems (R134A, R12, R22, R404, R410A) when used with a separate air compressor and a compatible cleaning fluid. It’s built for repeated use, offers several spare fittings and a 3-year warranty for confidence on service jobs or DIY maintenance.

How does the YUANRI flush kit safely manage pressure during operation?

The canister includes an adjustable pressure relief valve plus a pressure gauge so you can set and monitor working pressure. A built-in automatic vent helps prevent overpressurization while a hex wrench adjustment enables precise pressure control for different cleaning tasks.

• Adjustable relief valve with hex-wrench tuning (do not exceed 150 PSI working pressure)
• Automatic vent at about 170 PSI to reduce risk of overpressure
• Included pressure gauge for real-time monitoring
• Recommended use with an external air compressor (not included)

What components and fittings come with the kit and how do they help?

The kit is supplied with the stainless canister, reinforced hose, flush head and multiple spare adapters to fit automotive and household A/C service ports. Extra O-rings and gaskets are included to maintain reliable seals during repeated connections.

• 1× 1000 ml thickened stainless steel canister for corrosion resistance
• 3.5 ft PVC braided hose rated to 600 PSI working pressure
• Flush head with tapered rubber tip for tight duct or coil access
• Pressure gauge, SAE adapter, two spare adapters, two O-rings and two plastic gaskets

Which systems and cleaning tasks is this flush kit suited for?

This canister is versatile for both automotive and residential A/C maintenance: use it for deep flushing of evaporators, condensers, tubing and ducts when performing part replacements, retrofits, or routine cleaning. It also works on refrigerators and other closed cooling circuits that accept a flush procedure.

• Automotive evaporator, condenser, and fuel-line flushing
• Household air conditioner coil and duct rinsing
• Preparation for refrigerant changes or component replacements
• Compatible with common refrigerants such as R134A, R12, R22, R404, R410A systems (follow guidelines)

How durable and serviceable is the equipment over repeated jobs?

The canister is fabricated from thickened stainless steel for improved corrosion resistance and strength compared with standard aluminum cans. The hose uses fiber-braid reinforcement to resist heat and pressure, and spare seals/adapters are included so you can quickly restore a reliable connection on-site.

• Thickened stainless steel resists corrosion and high-pressure wear
• PVC hose with fiber braid withstands extreme temperature and pressure
• Spare adapters, O-rings and gaskets extend service life
• 3-year warranty from YUANRI for parts and workmanship

Who is this for: The YUANRI AC Flush Kit is aimed at HVAC technicians, automotive service professionals and capable DIYers who perform refrigerant-system maintenance or replacements. If you regularly flush evaporators, condensers or ductwork and require a rugged, portable canister with adjustable pressure control and serviceable fittings, this kit provides a compact, field-ready solution. Note: an external air compressor and appropriate flushing solvent are required and not included; always follow refrigerant-handling regulations and safety procedures for your locale.
