Rossesay AC Flush Kit — Aluminum Canister Line Flushing Kit with Gauge, 35.4" Hose for Car & Small AC Systems

Rossesay AC Flush Kit is a complete, aluminum-canister cleaning system designed to flush refrigerant oil and debris from vehicle and small-system air conditioning pipelines safely and efficiently.

This kit combines a thickened aluminum canister, built-in pressure gauge, flushing head with a rubber conical tip, hose and multiple adapters so you can prepare lines, evaporators, condensers and other HVAC plumbing before compressor replacement or system retrofit. It’s made for technicians and competent DIYers who use a separate low-viscosity solvent and an air compressor to purge contaminants and residual oil from refrigerant circuits.

How do I set up the Rossesay AC Flush Kit for a line flush?

Setup is straightforward: fill the empty can with your chosen lightweight flush solvent (not included), install the rubber sealing nozzle or proper adapter, attach the hose and connect to an air compressor. Open the valve and monitor pressure as you flush—do not exceed 150 PSI to protect the can and system components.

• Fill can with compatible solvent; never use flammable liquids.
• Choose correct adapter (1/4" SAE or 1/4" NPT) and secure O-rings.
• Attach 35.4" hose and connect to compressor; use gauge to track pressure.
• Flush until solvent runs clear; relieve pressure before disconnecting.

What components are included and what are their functions?

The kit bundles the main aluminum canister, a pressure gauge for live monitoring, a flushing head with a conical rubber tip to seal outlet openings, a 35.4" hose, two adapters, spare O-rings and gaskets, plus a plastic storage box. Each part is chosen to make repeated flushing quicker and to reduce leak risk during service.

• Aluminum canister: thick-walled for pressure resistance and corrosion protection.
• Pressure gauge: real-time reading to keep operations safe and controlled.
• Flushing head & rubber tip: seals pipe opening and prevents backflow.
• Adapters and spares: fit common fittings and replace worn seals quickly.

Which systems can I safely flush with this kit?

Rossesay’s flush kit works with most automotive and small refrigeration lines: vehicle AC evaporators, condensers, suction and liquid lines, plus domestic refrigerator or small HVAC pipelines. It’s intended for mechanical cleaning prior to compressor installation or when decontaminating a system after component failure.

• Car air conditioning lines, evaporators and condensers.
• Small refrigeration and domestic AC plumbing.
• Fuel and related pipelines where solvent flushing is appropriate.
• Not for pressurizing refrigerant service ports with refrigerant gas—use only solvent flushes as directed.

Who is this for? The Rossesay AC Flush Kit is built for auto technicians, HVAC service professionals and experienced DIYers who perform system maintenance or component replacements and need a durable, reusable flush canister with pressure readout. It’s especially useful when replacing compressors, retrofitting refrigerants, or recovering systems after oil contamination. Always follow solvent safety guidelines, wear protective equipment, and use a separate air compressor and compatible flush solvent as required by your shop procedures.
