Wayona AC Flush Kit — 1L Stainless Canister Automotive & HVAC Line Flush Tool with 220PSI Gauge and 35.4" Hose

Wayona AC Flush Kit is an all-in-one pipeline cleaning toolset that uses a refillable stainless-steel canister, pressure gauge and fittings so you can safely flush refrigerant oil and debris from automotive and HVAC lines.

This kit supplies the hardware professionals and DIYers need to purge contamination from evaporators, condensers, lines and household fridge AC piping without buying single-use cans. The empty 1L stainless canister accepts your chosen flush solvent (sold separately), while the included hose, adapters and readable pressure gauge let you control flow, monitor bottle pressure and relieve excess safely. The toolset is compatible with a wide range of refrigerants and built to resist corrosion and repeated use.

How does the Wayona AC Flush Kit remove old oil and debris?

The flush process forces solvent through the system under air pressure to dislodge varnish, sludge and residual oil, carrying contaminants into a waste container. Because the canister is refillable, you can perform multiple passes with different solvents or repeating cycles until clear fluid exits.

• 1L stainless canister holds solvent for several flushes
• Heat-resistant 35.4" rubber hose reaches into tight routing
• Hose and tapered tip concentrate flow at fittings and evaporator ports
• Pressure-driven flushing is faster and more thorough than manual rinsing

Which systems and refrigerants work with this kit?

The hardware is compatible with most automotive and small HVAC refrigeration lines; adapters let you connect to both European and U.S. fittings. The kit itself does not include solvent, so choose a flush fluid rated for the refrigerant and system you service.

• Works with R134a, R12, R22, R410a, R404a, R502 and similar systems
• Includes 1/4" SAE, 1/4" NPT European and 1/4" NPT USA fittings for versatility
• Not supplied with solvent — use manufacturer-approved flush liquids
• Warning: avoid flushing compressors, expansion valves, orifice tubes, dryer filters, or accumulators

How do I operate the kit safely and monitor pressure?

Fill the canister with a lightweight, system-appropriate flush solvent, tighten all fittings, then connect an air compressor. Keep working pressure under the recommended level and watch the supplied gauge; an adjustable safety relief valve vents excess pressure automatically.

• Maximum safe working practice: keep compressor pressure under 150 PSI during use
• Built-in pressure gauge offers real-time monitoring up to 220 PSI range
• Adjustable relief valve opens around 170 PSI to prevent overpressurization
• Durable construction rated with high burst pressure for added safety margin

What pieces are included and how durable is the kit?

The set arrives complete and ready for assembly: fittings, spare seals and a storage box let you service multiple systems and maintain the toolset. Major components are metal and heat-resistant materials designed for repeated professional use.

• 1 x 1L thickened stainless-steel canister (leak-resistant)
• 1 x pressure gauge, 1 x 35.4" heat-resistant rubber hose, aluminum spray head
• Multiple fittings and spare rubber O-rings, spare tapered tip, leak-proof tape
• Plastic storage box keeps parts organized for fast deployment

Who is this for: The Wayona AC Flush Kit suits auto technicians, HVAC maintenance professionals and experienced DIYers who need a reusable, heavy-duty flushing tool to clean refrigerant lines, evaporators and related components. It’s ideal when you prefer a reusable canister system over single-use aerosol products and when you need a controlled, pressure-monitored method to remove oil and residue from closed refrigeration circuits. Note: this product does not include flush solvent or an air compressor, and it should not be used on compressors or certain internal metering components.
